Topolsky Reviews The Blackberry Z10 1 February 2013 bzamayo.com/topolsky-blackberry-z10 The Verge: The problem with the Z10 is that it doesn’t necessarily do anything better than any of its competition. Sure, there are arguments that could be made about how it handles messages or the particulars of its camera, but no one could argue that there’s a “killer app” here. Something that makes you want or need this phone because it can do what no other phone can do. That’s not the case — in fact if anything is the case, it’s that the Z10 can’t yet do some things that other devices can. Or at least, can’t do them quite as well. Sounds like the predicament Windows Phone has experienced since launch. Being “good” isn’t enough.
