A Review of Handheld Devices: PDA's, Smart Phones, Cellphones

The latest handheld gaming devices like the Sony PSP have games which have advanced 3D graphics and amazing sound quality. Moreover, it can play the AAC, WAV and MP3 audio formats and MPEG-4 and AVC video formats with reasonable quality.

Along with the features what matters a lot is the look of the phone. A very expensive phone laden with amazing features but with poor design and body won't be as appealing to the eye as a cheaper but attractive looking phone.

Moreover cellphones, the latest fad is smartphones mostly in the corporate circles. So what is the smartphone? A smartphone is a relatively large-screen, data-centric, handheld device designed for normal phone functions whilst simultaneously functioning as a PDA.
