As with so many things, it depends on what you use it for....
I like to take photos of the grandkids at play. It doesn't seem to matter how involved they are in their play, as soon as Oma brings out the camera, they start acting up, pulling faces, hiding behind their toys.... And they know that I have to look "through that little window" to take their picture.
I have am Olympus OM-D E-M1 mark 3; it has a fully articulating screen. I can sit on the side of the camera, but still see on the screen when to push the button on the remote cord.
That I move the camera around on the table doesn't seem to bother them, as long as I do not bring it up to my face. They have not yet caught on that I use the cord instead of the button on the camera to snap them. As long as I am not behind the camera they ignore me!
So for me: fully articulating screen is the best!

I have a 9mm fish-eye lens that doubles as a body cap. Or maybe it's the other way around: I have a body cap that doubles as a 9mm fish-eye lens.
I find it handy to have the camera "shoot-ready" at all times.
Also fun with the grandkids: It's happened a couple of times now, that they thought they were standing outside the view-range of the camera and when I showed them the picture, they were in it anyway!

You might have a look at the Olympus OM-D E-M1 Mark 3.
It has a setting specially for starry sky shooting.
I must say I have not yet tried it out myself. We live in the city and there's just too much light pollution here.
Note in the Olympus Instruction Manual I have for this camera says "Starry sky AF is available with Olympus Four Thirds lenses. It cannot, however, be used with lenses with a maximum aperture over f5/6. For more information, visit the Olympus website.
We're hoping to visit friends, who live in a rural area, later this summer and are hoping for clear skies them, so I can at least try out this feature.

I have a 9mm, 1:8.0 fisheye lens, for my Olympus OM-D E-M1, M4/3 camera.
I believe it was intended as a body cap and as such it is almost always mounted on the camera.
When the grandkids are around, it's a neat little lens to have some fun with!
When it's light outside, I'll go and take a picture or two and post it here.

I like it! Makes me want to get on my jacket and boots and walk through that field, enjoying the stillness!

With all these "rules" for composition, I have started to wonder where these rules came from.
I think most of us agree, that leading lines, thirds, etc, do help to make a well composed photo.
When photography started... no, go even further back, when painting started, there were no such rules.
It is my belief that artists, and later on photographers, saw what they judged was a good painting/photo, and used the content of those images to make the rules, because they worked in the existing images.
I think it is something our eyes have become used to, and so we judge an image that meets these rules as good, without even having to consider what rules were applied.
I hope I explained that in an understandable way! Pressing the shutter release button is easier for me than explaining why I press it at exactly that moment!

In-camera composition is one of the reasons I like zoom-lenses: I can bring in more of the area around the main subject, or less.
Yes, I know about the thirds and spirals etc. but never take the time to think about them when looking through the viewfinder. I move the zoom lens in or out, move the camera up, down or sideways, till what I see in the viewfinder pleases me, then I press the shutter release button.
I have yet to meet someone who is looking at my photos, saying something about not following these rules (and believe me, I have a few very outspoken photograhpy friends.

Considering that an image in RAW is just another file, yes you can!
If the file is too large to e-mail directly, download and install Dropbox (or another similar program) to transfer it from your computer to another one.
Dropbox is free, and I use it regularly to send photos or other documents to my sister and several of my friends.

My personal experience for 4 different books, has been with Blurb only.
I am more than happy with the finished books, and so were the recipients:
One was a wedding photo-book for our granddaughter, another one my sister-in-law's 80th birthday party;
a vacation in Jamaica for another sister-in-law, and then one more wedding, of my niece.
As you can see: varying stories, photos taken under very different circumstances; all the photos as well as the text I put between the photos, came out very well.
Right now I am working on my own "life story" and sorting photos to go with it, and when I am finished with that, without hesitation, I will send it to Blurb again, this time to have 5 copies of the same book printed: One for each of our four boys and their families, and one for ourselves.

I thing I have not seen mentioned is what the 4/3 lens really shows you.
Like I said earlier, I don't really care about the numbers on the lens, I care about what I see through the lens/viewfinder just before I press the shutter release button.
Considering the crop factor of 2 for Olympus lenses, what I see through a 60mm Olympus 4/3 lens has the same field of view I would see through a 120mm "regular" lens.

It is because of the field of view that I have come to like zoom lenses. By just turning the ring on the lens barrel, I can either include or exclude the lamp post on the side of what I see through the lens (reason I will often start with the lens set to the "middle" and then increase or decrease the focal length to get the composition I like in the image.
As compared to full frame, if I set my Oly 4/3 to say, 60mm I get the same field of view as my neighbour gets on his 120mm full frame. This is the main reason I don't care about crop sensor or full frame, I look at what I see through the viewfinder and when I like what I see, I push the shutter release button down.

Pleased meet you then, Dennis!
I own a 4/3 camera, the Olympus E-5. Heavy beast!
Since replaced by an Olympus micro 4/3 OM-D E-M1 - now used to lend to the grandkids if/when they want to take photos, and occasionally still used by myself.
Added now as well,the Olympus OM-D E-M1 mark 3.
I have a number of lenses with it, and while the mount on the E-5 was different, an adapter is taking care of that, so that I can use all my lenses om the micro 4/3's.

:-) I am not at all afraid for my camera to take a rain-bath! It is weather resistant and has already taken a number of showers.
But I myself, although I'm sure I won't melt, I do not like the rain! I am sure that there is a gnome or something out there, aiming the rain at my glasses, and without my glasses, or with them covered with raindrops, I can't see much.
Yes, I have even learned to keep my glasses on when looking through the viewfinder.

After using a small pocket camera for a while, I bought a 4/3 camera, the E-5. I was happy with what I could do with it (especially compared to the little pocket camera), but the thing weighed a ton; add a long lens and ... well forget it!
Since then, I first bought the OM-D E-M1, which my grandson is using now. With that camera I have bought (and been given for Christmas, birthday) a few M4/3 lenses. And also bought an adapter to be able to use the 4/3 lenses with this M4/3 camera. About the same time the OM-D E_M1 mark 3 was released, my grandson asked to borrow my camera - so it went to live with him, and bought the mark 3. Both of us are happy with what we can do with these two cameras, and neither of us worry about any crop-factor. If the marking on the lens says it is 60mm, then to me it is 60mm; if the marking on the lens say 60-300 mm, then to me it is 60-300mm!
The important part to me is not what numbers are printed on the lens, although they help to pick out the lens I want to use. The important part is, what I see through the viewfinder just before I press the shutter release button.
Comparing my Oly M4/3 with a Nikon or Pentax or whatever other brand, is like comparing apples and oranges; It is what I see through the viewfinder that really counts, not what the markings on the lens tell me (or don't tell me).

Tulip?
Even at this stage I still admire the beauty of nature. Our planter is between the patio and the sidewalk, right now the white azaleas are beginning to open their flowers, but even when they are finished showing their white beauty, they still show a beautiful rusty colour, and are a great topic of conversation! Perfect too, for getting to know our neighbours when we first moved her two years ago!
As soon as it stops raining, I'll be out on the patio again to take photos of these flowers. Want to try some close-ups and macros!

The fun side of our beautiful English language, no wonder new immigrants (myself included, some 50 years ago) get confused :-)
