Do you think BBRY BB10 will be supported 4 years down the road?
Sometimes I envy AAPL that they support their old devices up to 4 years. Example is 3GS. it came out in 2009 and their last OS update is iOS 6, which ends in 2013. . Considering iOS 7 would at least have a year lifespan, so with iPhone 4 came out in 2010, 4S in 2011, 5 in 2012, 5S in 2013, and 6 in 2014, now you see the 4 gets up to minimum 4 years. My iPhone 5 would at least last until 2016 before I have to upgrade.
Would BB10 (Z10, Q10, Q5) would be obsolete a year down the road? I don't think Z10 would still get a SW in 2017, I think 2014 would be done...
Considering how BBRY SW is distributed via carriers, once it's end of life, I do not think these handsets will be supported by carriers anymore.
that's why even though I like BBRY, I still own iPhone because of its longevity, and this is why people are fleeing BBRY partly because no SW support.
