Can a smartphone be too small?

12.12.2006
Samsung's BlackJack, available from Cingular Wireless, is the latest of a recent glut of smart phones costing around US$200. Others include Nokia's E62, Research In Motion's BlackBerry Pearl and the LG enV. This particular device is quite attractive. In fact, one of its most attractive features leads to an unusual question: Can a mobile device be too small?

This 3.5-oz., Windows Mobile 5.0 device is light, has a great feel and is small enough for shirt pockets. The 2.2-in., 240-by-320-pixel screen is surprisingly bright and viewable given the overall tiny size of the device, and 3Gbit/sec. download speeds made getting mail and other media a breeze.

This device has quad-band support for GPRS/GSM networks and support for the faster data speeds of HSDPA 3G service in 1900 MHz range of spectrum in the U.S. It also supports Bluetooth 2.0 and sports a QWERTY keyboard and a thumb wheel for quick access to the menus.

Business and advanced communications features include instant messaging from MSN, AOL, and Yahoo, and mail clients from Microsoft and Good Technology, as well as Cingular's Xpressmail service. And, of course, it syncs personal information and documents with your PC and Microsoft Outlook. There's also extra storage in the form of a microSD slot.

For fun, media features include a 1.3-megapixel camera, access to the optional Cingular Video and Cingular Music services, the mobile version of Windows Media Player, and support for WMV audio files and MPEG4 and H.263 video.

In other words, the BlackJack is both cute and packed with features. But has it, like some of its competitors, gotten too small to be comfortably usable?
