One of the writers for Engadget, Brad Molen, a non-BlackBerry guy, has dedicated a full month to the Z10. He just covered MWC in Barcelona using the Z10 as his only phone. Back to BlackBerry: international travels
Here's where he lays out his 30-day plan to immerse himself in the Z10: Back to BlackBerry: One editor's 30-day trial run
Overall a very positive piece. And considering he took an Android phone with him in his backpack as a backup device in case he couldn't stick with the BlackBerry for all of MWC, that's saying a lot. I'm really itching to try the Q10 when it arrives and this review gave me even more reason.
