OS2008 of N810 is actually Maemo 4. You can transfer files to it with USB-stick, find only right type of microUSB-USB A -cable. And remember you cannot charge with USB-port you need small round-connector in Nokia charger cable. If you want program it here is good tutorial: http://maemo.org/development/documen..._4-0_tutorial/ Also you can start where I started with 5 years ago: https://talk.maemo.org/showthread.php?t=99982 user endsormeans knows lot about it, his signature has good linkis. After you have readed those..you start think why Nokia didn't put mobile data in it and then you start think why not somebody make N810 upgrade board these days, because the form factor is one of the best.. And it is usable nowadays...it will be timeless classic.
