gotten to spend a few days with the update. love the UI tweaks and look for the most part. really like the revamped dialer and app drawer. might actually end up keeping this thing stock for a while (who am i kidding?

).
only annoying bug that has cropped up it that after making a phone call in the car dock, for some reason, once i take it off, the phone defaults to speakerphone mode. minor inconvenience though
That'd be because the default mode to answer whilst in cardock mode IS speakerphone.
Some guy got lazy and forgot to put in a line of code to make it auto-off.
Moving on:
I was on .588 for awhile. So, I will cover the differences from that leak to the current REAL official build (as most people are probably already aware of the obvious changes from froyo to ginger)
Sadly there was no easy way for non-rooted users to upgrade their software. So just as many did I had to use RSD lite and SBF BACK to froyo, then pull the OTA.
It was okay, minus several apps in the market not existing to that specific build. Thankfully this newest build fixed all of that.
It was also slow on the keyboard. To the point that I could type out two sentences before the phone actually inputted it. It would buffer the whole dang thing. Very annoying when you find out you made a typo a paragraph back 0_o; Thankfully that has also been fixed.
Overall speed has also improved from .588. That is a big plus as it would lock down easily.
I didn't have any problems with maps E/W switching. Only with my actual GPS receiver going on the fritz. I blame .588 for this, as it has now been solved. (despite the ignorance of the verizon wireless employee who told me my phone wasn't a "satellite" phone and had NO GPS communication, idiot).
So my speed is up, all my apps are compatible. My amazon store had all my apps in it no problem (Although the market didn't re-download ALL of my old apps, just a strange selection of them. Oddly lacking facebook and such). My GPS is working like a charm.
So there we go
