Yup -two here...
I've got mine after seeming my MOM use hers (ineffectively). I sat down and began playing with it and said- holycow this thing COULD rock. so I got a used one a few days ago and took it apart and customized it. I went from an ol' Moto RAZR V3 (various versions) which I hacked to pieces (all of them) and handed out to friends and family, to this.
Currently experimenting with WM6.5 but so far I think 6.1 is best: more support and themes from what I've found. I just love the keypad- it's not too small, but it's tiny regardless. Amazing little phones. The worst thing about it is that lack of a 1/8" headphone jack. I mean, even with the battery hacks, I want to sit and do stuff and STILL have a conversation while plugged in. I can of course, but why not have the 1/8" jack? HTC got smart with some of their other phones and put that in. Data+Voice at the same time is critical. Might have to go with a newer smartphone eventually.
For now, it rocks.
