Great review, very informative. I noticed a few areas where you were reviewing WP7 Mango rather than the phone itself, but that's understandable given that the OS is the basis of the phone.
Some bits you missed (or I somehow missed):
-battery life: always important, one of the things everyone wants to know.
-video playback: on a screen that big you know people are going to want to hear about how movies look.
-sound quality: not a must for reviews but it's always nice to hear if the speaker is good or bad.
Other than that, very nicely done, I'll be looking at your channel for future reviews.
