I bought the 02 Atom over a year ago and it's been pretty helpful. It works as a PDA, phone, camera, music player along with having many diferent functions. It is a really good all round device, (not as good as the iPhone of today) but has all the capabilites of one. It is capable of work affiliated requirements like viewing documents, accessing the internet (wirelessly) and email, calender and many other things. It uses a touch screen only which you use a pen to write on. It is good, but gets pretty difficult because you have to write everything then wait for it to load and realise what you're trying to write which it commonly gets wrong because it isn't programmed for any one persons hand writing. The pen system gets a bit tough as it means wherever you are, be it just at home or at a party you have to whip out the pen and type out what you need to say or to type a number. Either way It gets difficult. Other then the problem with the keyboard system, the phone has great features and capabilities and even after a few years can still be regarded as quality.
