Like the features - Hate the new look
I liked the black boot screen with the Chrome design in the center, but the new boot screen, login screen, gmail, and Google Docs pages are ugly. The lack of color and pale highlights make the pages difficult to read. My husband thought I had screwed up the contrast, until I told him it was like that on his computer, too. Also, icons for apps are now giant and I can't figure out how to reduce their size. As you can tell, my gripes are aesthetic.
But not all is negative, I like the new App Store and the New Tab page (minus the giant apps).
