I'm being advised against it because of the lack of space, but space isn't an issue too much for me...
aye some of them just have system ram and whatever size SD card you put in and not much else, but we have been living in a world of divx mp3 and others for so long its hard to think we'd ever have something that small knocking around without it being filled in the first five minutes of it being switched on
yet most of us remember when games came out on a single floppy
and even if 20gb wasnt enough, they all have usb slots, so thats every usb memory stick you have as another drive, external hard drives and in my case the 160gb ipod (although i wouldnt be able to sync with it as you need the songs on the laptop to begin with)
