Finished installing Win 8 on my laptop along with a new SSD (840 Pro). While I'm not exactly happy about the lack of the old start menu, I still like the new look.
The text is much easier to read, I also like that they got rid of the transparent stuff, it's a bit more responsive than Win 7 (I tried both on same setup/same SSD).
However I'm not changing to 8 on my main PC, the only reason I installed win 8 on my laptop is because I got it for free.
