After 4 years, my fully up-to-date XP install got completely messed up so given Win7 was so close, decided to try the RC rather than go back thru multiple XP updates/patches. Yes, I know it is an older laptop but it does have 1.25Gb RAM. I ran into the Intel GMA855 graphics lack of support but the forums here got me through the fiddle to get the Vista drivers running. OK, some of the Dell utility software is no longer available so some of the dedicated Fn keys no longer work but I rarely used them anyway. However, the big gotcha right now is battery and power management. Battery life has been decimated because cpu throttling does not work which is a killer when running on battery alone. It is stuck at 1.6GHz whereas under XP, throttling regularly dropped it back to 600MHz. This one alone may be the one that stops me bothering to upgrade on Win7 on this laptop. But it would be nice as generally, performance seems smoother although much of this may be due to only installing the minimum required stuff.
