Maemo and the N900 are on page four of TFA.
There are lots of "diceless" systems - basically rock-scissors-paper variants.
I have this wonderful image of a 6'2, 300lb tattooed muscular prisoner whining about whether his 58th level paladin's holy sword being destroyed by enchanted rust-monsters.
I actually think games like D&D are a very good thing for prisoners - it teaches a variety of new ways to interact with people and non-violent ways to let off aggression.
I've just finished building a new website for a startup and mobile was a consideration from the start. As a result the page content is all modularised and there is a layout+css switcher for mobile devices. Some of the fancy stuff doesn't work as well or look as good on the mobile site but all the functionality is there - with and without JavaScript (progressive enhancement really comes into its own here). This means that going forward there is only one site and two layouts to maintain, a vast improvement on the last time I tried to retro-fit mobile layouts to a site and settled on a similar solution to the parent which is essentially to build a second site.
I'll echo other posters by saying that
