I dont have much experience with 2007 but 2008 looks so much better than 2007 ever did, the transparent applets on the homepage look great. Microb as the browser with the adblock addon installed works fantastic and makes browsing quick as there are no more ads and full javascript support means most websites work perfectly. Flash 9 works great and youtube can be viewed at a pretty decent speed. There are a lot of other improvements from what I can tell but these alone are well worth it. I am very impressed and would not downgrade back to 2007 now.
