well it is unlikely linux install on PC will update also your BIOS (which is similar to what n770 firmware does) Also updating PC with 250mhz cpu, 64mb and 128mb slow harddisk with on the fly compression might take ages. Also when something goes wrong with installation on PC you can just boot from floppy or cd or move disk to other machine and fix it. it may be much harder with your previous tablet and new paperweight :-)
