The number of OSes that can be run on N810 Internet Tablets just grows and grows. Now it's time for MS Windows family. I hope you still remeber Windows 3.1. The trick to run it on NIT is to use DOSBOX utility - x86 PC emulator (the instructions may be found e.g. here or on Internet Tablet Talk forums). What's more interesting, there's a proof that you may also run Windows 95 this way, but don't expect that it will start and work smoothly (you really need to be patient). Thanks to very active Internet Tablet community, you can also have MAC on MIT by using the Basilisk II Macintosh emulator (list of Macintosh Software that can be run on a NIT and instructions).

Purists would extend the list of working OSes by adding Android, Ubuntu and numerous emulators (all ported to maemo) like Amiga 68k - UAE, Apple II - Winapple, Commodore 64 - Frodo, Palm OS - Access GarnetVM, TI-89 Calculator - TiEmu 2 (just to mention the most interesting ones). Can you do this all on iPhone?

So now, the "open platform" slogan gets completely new dimension...
