i installed ubuntu 8.04 today on my external usb hard disk. :yahoo:the installation took less than half an hour and later it took me another half hour just to get wifi working properly, had to get the proper drivers. would have been faster, but downloading from the repositories takes so much time.i thought the system would be a bit slow or would atleast face occassional lags since its on usb. but i was amazed to see how fast it is. there are absolutely no lags. im running it on a HP laptop with full visual effects. dunno how compiz would work on the geforce go 6150, havent tried it yet.downloaded a few updates recently and it took so much time. it downloads at around 10 KBps, even low many times. im happy that it works well on my usb external hard disk. now i can carry around my OS. :yahoo:compiz working good.
