BlackBerry diehards will lament the lack of a physical keyboard _ they'll have to wait for the Q10, a model in the more traditional BlackBerry form. That's due this spring. But before writing off the Z10, these loyalists should try its on-screen keyboard. It's really very good. It provides more vertical space between the keys, imitating the steel bands that separated the hardware keys on the BlackBerry Bold. It's very accurate and easy to use.
The Z10 will also have a replaceable battery, something lacking on the iPhone. Screen quality will be good, too, at 356 pixels per inch, compared with 326 for the iPhone 5 and 306 for Samsung's Galaxy S III. Unlike the iPhone, the Z10 will allow you to expand storage with a microSD card, and it sports a chip letting the phone act as a credit card at some payment terminals and share data wirelessly when tapped against some other phones. The Z10 is heavier than the iPhone, though _ at 4.78 ounces to the iPhone 5's 3.95 ounces.
So why does the Z10 and BlackBerry 10 face such an uphill battle?
