Just upgraded my Dell Vostro 1500 to Ubuntu 10.04 LTS on Saturday (May 8, 2010) and so far I love it!
I made the upgrade because it is a LTS (long term support) release, but the main reason was, I was having issue with my wireless connecting to U-verse. I am happy to say, the upgrade has seem to resolve my wireless connectivity issues. I can go back to watching Bleach in my bedroom if my wife wants to watch something in the living room (I am on episode 263, 幽閉？！千本桜＆蛇尾丸).
Other benefits of the upgrade include:
Faster boot time (it seems to be faster to me)
Better looking default desktop and style
Sound working out of the box (even Flash sound in Chrome)
Over all I am loving the upgrade. Nice work Ubuntu team!
