Microsoft Windows 7 Home Premium

I've been using Windows 7 since its beta release, but my laptop's been running the final version for weeks now. I really disliked Vista and preferred XP still, but Windows 7 has tipped the scales...finally. Windows 7 has been reliable and it's snappier than Vista. Windows 7 sips laptop battery power so my 1-year-old Dell XPS M1530 runs longer under Win7 than it did under Vista.
