So... my take on Windows7. It "feels" much faster than Vista, as responsive as XP. However, it seems that software runs no faster: I get identical FPS in Crysis for either Vista or Win7; same time within milliseconds in SuperPi. The XP Mode is a neat idea, shame it would not work on the software I tried. (Either told me to insert the CD or told me it could not initialize.)
I am not a big fan of Windows Media Player 12. I am a fan of the fact that Vista Glazz is no longer needed, as now the task bar is always transparent. I am unsure how I feel about the new pin to taskbar feature, but I dislike the lack of quickstart. The new start orb is cool though, as is the new Windows-is-booting screen. Also nice is adjustable UAC (rather than "on" or "off," you now have four levels of intrusiveness to chose from) but I will likely run it on high.
It is nice to see that Microsoft finally got around to expanding the Experience Index, but I think they are a little screwwy:
A Deneb is better in the scheme of all processors than quadfire is in the scheme of all video cards? Last I checked, 2x HD 4870x2 is the third best solution (after 3x GTX 285 and 2x GTX 295), so why is its score so meager? For the record, that hard drive is my 80 GB SATA-150, which is why the score is so pathetic.
