Actually I wasn't really referring to the actual computer hardware but peripherals (printers, scanners and other external ICs) that are problematic. Built in stuff, if it's reasonably new should hopefully work (but there are always those pesky Audio and Video drivers that are a pain).

To date, I've had one and only one driver issue - there's no 64-bit version of the JET OleDb driver for Excel (though there's a workaround)

Maybe I've just been fortunate, but I haven't had an issue with any peripherals.
