I hear what you are saying RJ but why not make use of some thing you already have without reverting to another device to make up the deficiencies of the first device. Folks read things all the time on their iPhone screen. What about being able to bring up a ND conversion chart without having to go to your phone or dig out a printed cheat sheet.... I am sure there are lots of Ideas folks on this site could conjure up by thinking out of the box a little. The whole Idea of my post was to think a little unconventually.

Flickr is free, whether the images can be viewed-only or available for download is simply a matter of how you set the privacy settings on the images when stored to the site. The "free" limit is only how many you want to upload per day or keep on their site in total. The technical skills needed of your target audience is low as most of your audience will typically be view-only. To share you just need to send a URL link to all the images, or to individual albums should you organize the images into albums, such as 1 per game, etc.

As an ex-lab guy who ran both silver halide printing operations and inkjet printing operations (and electrostatic and dye sub...), I have to say the answer comes down to this set of questions:

What sort of volume do you anticipate, and with what sort of frequency are you going to want to print? How important are controls over color, privacy, paper stocks, and time? Do you want the best archival results? Do you want to print directly from Lightroom so you get the widest possible color gamut? How good is your monitor, and do you calibrate it and profile it monthly with hardware and software from X-Rite or Datacolor?

For Black-and-White, I'd prefer one of the Epson P-Series — The P400 has two black inks, plus Cyan, Magenta, Yellow, Red, Orange, and a Gloss Optimizer. That's so it can print on both glossy and matte surfaces. The larger P-Series printers use a more advanced configuration for a wider color gamut and finer B&W gradation. They're pricey, but pretty amazing.

For most hobbyists or pros who need to do some in-house printing, the Canon Pro-100 is fine for what it is — a great value. I don't have one, but have seen excellent results from them. This forum may help you decide:
