Could not agree more.
The resize from-every corner is the only Lion feature I miss...
Have been to Lion and ML, have come back.
Once Mavericks is at 10.9.2 I'll have a go (Clone disk->update->Try).
I'm looking forward to some of the OS optimizations, but honestly most of the new features Apple has offered in mavericks fall flat with me:
iBooks? - Excuse me, I have iBooks on the iPad, why would I want to read books from a MBP/MP?
Maps? - can't see the point on a computer. iPhone/iPad? yes. Mac Pro? No.
New Calendar? - Switched back to a paper calendar 18 months ago. The main problem with electronic calendars just can not be fixed with an update.
Safari? - Nice, but I'm making do with 5. Just as with a larger tv: the programming does not get better...
iCloud keychain? - for an iCloud user it this is probably a good update, but I'm using neither keychain nor iCloud...
Multiple displays? - wait. Didn't mac support multiple displays since way back in the 80's? Oh yeah. This means they "fixed" the "feature" they "introduced" when allowing full screen apps...
Notifications? - no need.
Finder Tabs? - Long overdue, but not really necessary for me. I installed a trial for Totalfinder once upon a time, and when the trial expired I didn't consider it worth the money.
Finder tags? - Wait, this is an improvement? I think it's a disaster waiting to happen:

"Advanced technologies"? - Some of these are interesting, others less so, but definitely among the few real reasons to "upgrade".
Honestly, I'm a recovering UI designer/programmer and since I returned to the Mac in 2006, I've regularly sent suggestions to apple about potential improvements to the OS, especially to Finder. In all these years exactly one of them has been realized (flexible resize). In all the other cases, post snow leopard, OS X has moved farther and farther from my ideal...
