Buttons and Keypad Layout Although important for almost anyone; the layout of the keypad is really important for SMS junkies and anyone who needs a PDA phone. Although the basic number keypad in conjunction with T9 works wonders for typing out text messages if you’re looking at sending emails (which will typically be much longer) than you may need to look for a cellphone with a QWERTY keypad. Regardless of what you choose, keypad layout is tantamount, as a badly laid out QWERTY keypad is much worse than a decently laid out number pad. Tiny Keys Some keypads may look cool and funky but may be a nightmare to use. Sometimes tiny keys look neat but they may be an ergonomic nightmare. The best keypads have adequate (not extra) spacing between the pressing the keypad results in a definite feeling of pressing a key; this is called positive feedback Large Keys and Bevilling Some keys are rather close to each other as shown above but they still allow for ergonomic working. The raised portion in the middle is called bevilling and allows your finger to feel each key; which is an integral part of properly using the keys QWERTY Keypad These keypads are suitable for typing out longer SMS’ and mails. But the keys should be properly spaced and large enough to operate with both thumbs. Besides this bevilling is also important Pseudo QWERTY Keypad A new and space saving concept, where one physical key represents two alphabets. Such keys work similar to a rocker switch where pressing on either side results in a different key press. Key size and bevilling are of utmost importance here. Memory Being highly personal devices we store a lot of data on Mobile Phones. Be it the mundane SMS’ or MP3s, videos and photos, storage space is a much desired element of any cellphone. Some of the higher-end cellphones are coming with a lot of memory onboard; to the tune of eight and even 16 gigabytes. Most of the phones do not come with this kind of memory but have expansion in the form of SD, microSD and miniSD. When buying a multimedia phone please ensure your phone has at least 512 MB of available memory, whether integrated or in the form of memory card expansion. This ensures you can store your collection of photos, music and so on. There is nothing more annoying than running out of space. SD, miniSD and MicroSD The most common flash standards, SD is the oldest and largest form factor. MiniSD and microSD have been spawned and recent advances mean you can get a 16 GB microSD card; which means 16 GB on the size of your thumbnail. Flash and Camera Cover Useful additions; a flash makes indoor shooting a little better. Xenon flashes are rare; but worth the premium over even dual LED flashes which are practically useless. A camera cover protects the lens from dust and grime.
