On a normal Ubuntu 10.04 desktop installation on x86. Am I correct in thinking, if I move country etc.. I can just take the hard drive out and plug into a new host machine wherever I go, it doesnt matter if first machine was really an AMD/2GB/SATA/Foxconn and next is Dell/Intel/4GB/Supermicro ? With the exception of maybe reconfiguring Nvidia/AMD setup?
Equally once I get my desktop setup with all the tooling (several hours) etc.. rather than redo the same on the laptop I'll just raw copy the image across to a partition on the laptop and install grub / setup mbr.
Linux will redo detection each time at startup unlike win7/vista and wga etc..
