I just finished installing Windows 7 and I gotta say, I'm pretty impressed. I've installed a few programs now with ease. There's a few things to get use to but overall, it looks pretty solid already. Things I did notice (even after installing my huge programs like a few of the Adobe products) was that the boot times have dramatically gotten better. It takes me around 10 seconds to fully shut down. As for starting up, I'm not quite sure as I didn't really pay attention to the timing of it but it seemed much faster than XP and Vista (I've installed both on this system). I also noticed my programs running faster and Firefox seems to be loading web pages much faster than before. The only thing I don't really like is the taskbar. Having the images there makes it look like they are copying off of Apple (anyone surprised?!). I'm going to look around to tweak some things but when I disabled the image display that comes default, I didn't like the way that looked either lol. So far everything is running smoothly on it as well. I've installed quite a few large programs and had 0 problems so far. I've even upgraded my firmware to my DVD burner and now I can burn media that I wasn't able to before so I'm really effin happy right now lol. Overall, I give this OS a 9/10 [so far].
