Is this also true for other archiving/compressing standards?

I own a Dell Inspiron Laptop designed for Windows ME (yeah its that old) but the harddrive is broken. I tried to run SLAX operating system by taking out the harddrive and inserting the flash drive and then turning on the computer... then i get the dreaded message:

Operating System Not Found

Its the same message i got when i first found out my harddrive broke. Does anyone have any idea how to make my laptop work, please... That, besides my windows 95 desktop which serves no purpose except to play solitare and hearts and pinball, is my only computer.

I'm looking for a media device with the following features.

  • at least mp3, vorbis, aac, and wma
  • for videos vorbis, mp4, wmv (wmv doesn't matter as much)
  • not too big, but it should have a reasonable screen for videos
  • good podcasting support
  • linux support
  • hackability (eg. write apps or games for it)
  • it would be nice if it suppoted WiFi

Does anyone know of a device like this?
