No, it shouldn't. I'm a techie who spent lots of time getting a Gentoo install running great on my Inspiron 1525, specifically built with all Intel hardware (wifi and video) knowing that their drivers were the best. Made a wiki for it and everything (it eventually got nuked when gentoo-wiki was lost, but that's another story). Then, one day after fidgeting with xrandr and various related tools to get HDMI output to my TV working properly, I gave up. I backed everything up because I was afraid of permanently giving up, then I went to Vista.
And you know what? Everything worked. Things that I didn't know that didn't work in Linux worked just fine in Vista. Examples:
- My sound outputs properly and didn't detect my two laptop speakers as the "surround sound" speakers. This would also change on different kernel releases due to new drivers in ALSA.
- Both of my headphone jacks worked. I always assumed one was just busted since it was a refurb, but nope, they both work fine in Vista.
- My wifi activity light doesn't blink off and on ever 3 seconds. I had to hunt down that kernel parameter to fix that in Linux.
- My second output correctly detected my TV resolutions - no more stretching 4:3, I had actual 16:9 output at 720p resolutions finally.
Don't get me wrong, there are some things I miss about Linux and I understand almost all of the above problems are driver problems, but they are still real problems that aren't fixed and won't be for a while. It still remains that *in my opinion* Windows is a better choice than Linux on a laptop for just about anyone except those who can't run Microsoft programs for religious reasons.
For the record, my battery life is roughly the same between Vista and Linux, although I do feel that I got slightly longer life out of my Linux install.
