What about those returning...I myself left BB for iphone 4 back in September 2010. I now have 4s and will be going back to BB for Z10. I left because I needed an all touch with a great browser...I believe (and have heard from direct sources) that BB10 will have best browser on market...OS is better than iOS and Android.
iphone is boring now to me and Samsungs are junk in my opinion (my mom, sisters and sister-in-laws all have them and I see first hand that they are junk)
BB10 will surprise a lot of people and the timing is actually perfect...BB will regain market share in the US, UK (Euro) and Canada...watch and see
Shorts be warned and best of luck to all in the New Year
