"Great call quality but lots for BB to develop still"

Had this phone now for three weeks. I also own the Note 2 (had for 6 months) and also the Nokia 820 (had for 2 months). I enjoy using different mobile platforms. However on occasion, over the last two weeks when it came to Web browsing and apps, I was very tempted to retrieve my Note 2 from drawer.
Z10 has sturdy build, premium looks - particularly on the black version. Sadly, I have the white version (the version I own) is devoid of the soft rubberized plastic battery door cover which is on its black version. Instead we have hard cheap feel plastic.
Browsing on occasion is erratic. Often it will crash, screen will blacken and become unresponsive for a couple seconds. Continue to swipe the blank screen and then the browser will jump back to the top of the Web page. You will then have to scroll down the page to get back to what ever you were reading. Frustrating quirk. Stability isn't currently a strength of this phone
I have found no way to quickly make a call from an open text / from text drawer. One has to specifically go to contacts/dialler/calls. Neither is there any facility for cutting and pasting numbers onto the dialler.
Call quality is fantastic. The Note 2 cannot compare. Media sound is full and loud - no complaints.
The screen is sharp, albeit a little dark at times. .However, sensitivity of the screen to swipes is erratic.
Apps (lack of...) is the frustrating part of the blackberry user experience. No flip book, no pulse or evernote...I am struggling. even windows 8 has evernote! Lots of app development required
On the subject of apps, the maps app requires lots of development. It is currently not safe to use its navigation facility. I tried it once on a long journey and got lost in the British countryside. I was forced to swap phones to my No nokia 820 - which as a reliable on board navigation app.
