One (to me major) improvement with 10.7.3: CMD-shift-S for Duplicate. Check it out- keyboard shortcuts are back in style. Now if only CMD-d for "Don't Save" was also enabled...
Also, it seems like TextEdit launch problems are gone. I was getting 25 second beachballing upon opening the app (multiple fresh installs on SSD, notebook HD, iMac).
iCal + AddressBook are still IMHO ugly, Versions and Autosave is as useless (to me) as ever, and the Duplicate workflow is longer and clumsier than before, but a tiny bit better thanks to a proper Duplicate keyboard shortcut.
To me, 10.7.3 is a tiny step forward from 10.7.2, but a TextEdit app that doesn't beachball on open is not exactly an update feature to be proud of at this stage of the game, six months after release.
Still on my wishlist:
-Autosave optional by app
-Versions optional by app
-keyboard shortcut for "Don't Save" in the dialog box
-optional less ugly ical/addressbook skins.
I'm not touching Lion on any computer I actually use for work until 10.7.4, and even then only if there's an Autosave on/off switch. Failing that, it's time to start looking seriously at non OS X installs for the next machines we add (and I get for myself). The good news: Avoiding Lion has already saved me over $1000 by forcing me to stick with my older MacBook Air instead of getting a new one for the better sound, better battery and extra snappiness.
Nuts that I want to buy a new Mac and for the sake of trying to force a few features I don't want/need Apple has given me good reasons not to.

Lion's problems are beyond normal bugs... for me its mainly ridiculous feature implementation.
Yeah, many of the Lion concepts seem pretty good but it's like the Detroit concept cars that show "Tomorrow's Family Car" with ultra-tinted slit windows and running on rubber bands. Looks good to the designer but not at all what you need to get to the grocery store or for a trip on the highway to the office.
