I upgraded to Lion the day it was released and I love it. Sure there were a few things that are done a little differently, but nothing that will take a long time to learn.
After a few weeks, I went to one of the free Lion workshops at the Apple store nearest me and it was MOST informative. I did learn a lot and also found out how to change some of those new UI issues that people talk about like the reversed scrolling. At first I thought the workshop might be a waste of time going over things that I already knew, but it wasn't at all like that and there were quite a few things to that I learned.
What may be annoyances or bugs to others may not be to you. The only issues I have really had so far is with Microsoft Office:mac and from what I have read Microsoft isn't making many plans to upgrade Office:mac to address the issues with Lion so I am turning more and more to iWork and loving it. Most every other application I use either has been updated to be Lion compatible or I have not had any issues using it with Lion.
