This PDA is very good at being a mobile office, but lacks the ability to be flexible in other applications. As a glider pilot, I use a PDA to navigate and log my flights. The HP iPaq can be a bit of a beast in the way of running other applications than those pre installed, but it will. The useful applications include the microsoft office software which is incredibly good and reasonably similar to office from a couple of years ago, just on a smaller scale. The features are not as plentiful as the computer version, but you would expect this.
If somebody were to purchase this PDA, I would heavily recommend buying a large accompanying SD card for any other programs as the internal memory isn't great. It could easily require so much more memory, but it is generally enough for using the PDA for the normal office type jobs.
The display on the PDA is very vivid and bright and the touch screen responsive. With the ability to surf the net too, the PDA works well at displaying web pages but can be slow to connect to a Wi-fi network (sometimes taking in excess of 5 mins). The bluetooth however is plenty more responsive, usually connecting in a matter of settings to a manner of devices such as a mobile phone or mobile GPS (as I use it for)
The PDA has a very reasonable battery life, lasting more than 2 or 3 days in economy mode, but again, the more it is used the more it will run down. It has helped me dramatically with organisation and keeping track of important dates. Another drawback, however, is the fact that when the battery is fully flat, it takes a long while to recharge and requires the USB plug in to start this process rather than using a plug, which can be a pain in the rear end, especially when the USB lead is more than a 3 hour drive away. Overall it is useful, but no match for a smartphone of today.
I brought this product as a refurbished, off ebay, for £180. It isn't the thinest of devices, or the lightest, but it will do. The screen is big enough, and it has all the right features, WLAN, Bluetooth etc.
There are a few glitches in it though.
After a month or so of having it, the touch screen messed up, part of the screen just would not function. So I phoned up HP, and they gave the Collect and Return system, which is useful, as it meant I didn't have to post it myself! It was sent off to hungary, took a while to get it fixed because "the part wasn't in stock", so, after about 6 weeks, I got it back, and wah hey, it's working again.
So, any other problems? Yes, the long lasting problem with the battery, where the battery doesn't last so long! If you switch it off, it randomly likes to turn itself on, and waste battery. There is a 'fix', but it doesn't work. So, each time I am not using the device, I take the battery cover off, which stops the device from working.
Ok, now the good side to it, it is good for playing videos, music etc. Get hold of Opera Mobile web browser (costs extra), and you'll have a great web browser. Internet Explorer isn't too good, it's quite slow, and can make the device freeze.
You can do a fair amount of things on this device, but what you can or can't do, and what is good/bad is from now on down to Windows Mobile 5, which would be a completely different review.
