Dell Axim X-30:
This PDA is a great little device that served its function well until the current crop of smart phone have completely out done this device. There are many reasons why smart phones are now the way forward. For starters the battery life on this device is rubbish, I ended up with 2 extended batteries to make sure that I made it throughout an entire day at university while my phone lasts 2 days without charging.
To get internet on the PDA I had only wi-fi access which whilst most of the time was sufficient there were many times that I needed it but could not get a signal in my current location, now with a phone I have mobile internet as a back up option.
The touch screen on this required me to use a stylus, whilst I got on well with the stylus it was a bit fiddly to type long messages with and the screen was not amazingly responsive and the stylus had a tendency to go missing, on my phone I can type quickly using a multitude of keyboards with which I can type at a good pace and use my fingers which I have yet to have go missing.
The market for games and apps for the windows pocket operating system that I have installed on the device were quite limited and although there were a few good games out there (e.g. Age of Empires) none were free, with my phone I can now install a selection of thousands of apps and a lot of them are free (and those that aren't I can try for 24hours).
Another area in which I now realise that the PDA was lacking was customisation, the so called home screen had very little ability to me modified beyond adding the events in my calendar etc whilst my phone I can do pretty much whatever I like with.
So now I would only recommend this device for people that are not able to afford a phone like the HTC Hero etc which far out perform a device like this which is really outdated.
