I may think BlackBerry is something like Apple who use all its own product for its Smartphone? Because of its own OS BlackBerry 10 for its Z10 or Not because of 1.5GHz Qualcomm S4 Plus Processor which is not its own product like Apple’s 1.2GHz Apple A6. In front view both Apple iPhone 5 and BlackBerry Z10 look like similar but other high-end Smartphone are very giant in look than iPhone 5, Lumia 920.
As per hardware and software specifications and features it is not that impressive because its specs very much similar to all other devices. Only Speciality in BlackBerry Z10 is that its own BlackBerry 10 latest OS.
