wait until reviews... an update is just released... in a few hours people will post reviews.
The curent build is REALLY not great, and i had it on my daily driver... while staying in UK this weekend (i hoped for update last thursday) it took me 3 hours to send a recording (mail attachments didn't work... file picker didn't work etc). after the device rebook, it took appx 10 minutes for the SMS app to work. and even after that it took as much as 30s to load an sms (sometimes you had to close the app and try again)
Let's hope this build is way better. trust me, WAIT for reviews!
