Thoughts on the installed update:

1) Yes, it does appear to be snappier (measurably faster, 20-30%) _ONCE IT'S LOADED_! It does take longer to boot. On average it takes almost exactly twice as long to boot.

2) Installation took just shy of 4 minutes (3:53 by my non-scientific reconning. I was using the HTC cable...anyone else actually time theirs and use some other USB cable?) I sincerely doubt that the cable matters unless someone was stuck at USB 1.1 but you never know for sure unless you ask.

3) GPS is working fine for me so far with both Google and Bing. I did have to sync (of course) but my average satellite count in Google is 7.

4) Initial memory utilization was 65% after soft boot (immediately after flash) but dropped to 50% after hard boot (long hang up press).
