BlackBerry Z10 and Q10 smartphones make their debut

One phone, dubbed the BlackBerry Z10, features a full touch screen -- no QWERTY keyboard on this one. The 4.2-inch display has a pixel density of 356 per inch, compared to the iPhone's 326ppi density.
The other, dubbed the BlackBerry Q10, includes a full keyboard similar to those on older versions of the BlackBerry.
"We have the aspiration to be the best keyboard experience period," Chief Executive Thorsten Heins said during an event in New York.
Both devices include 4G LTE capabilities. Verizon Wireless said it will offer both phones to its customers. The Z10 will be available for $199.99 with a two-year contract in either black or white models. The white version is exclusive to Verizon, the company said.
The BlackBerry Z10 will hit several markets by early February, but U.S. buyers will have to wait a bit.
"We expect availability for most U.S. carriers for Z10 to be in March," Heins said.
Along with Verizon, AT&T, Sprint, and T-Mobile will also offer the phone. Heins noted the carriers will soon announce their plans for the devices. The phone will retail for $199 with a contract or sell for $599 unsubsidized, the company said.
U.K. buyers will be able to purchase the phone tomorrow from EE, O2, Vodafone, Phones 4u, BT, 3UK, and the Carphone Warehouse. Pricing varies based on carrier and retail partners and is available on pay monthly contracts and pre-paid tariffs.
The Z10 will be available in Canada on Feb. 5. Pricing will vary by carrier partner but will retail for about $149.99 on a three-year contact.
Heins, meanwhile, discussed other features of the new products and operating system, including BlackBerry Flow, which allows users to move between apps. The technology allows users to open and minimize apps through swipes, and everything keeps working. BlackBerry Peek allows users to play a video and check notifications at once.
