The HTC Touch Diamond is a solid Windows Mobile smartphone. The HTC Touch Flo 3D interface makes using the device far easier than having to rely solely on Windows Mobile.
However, since it's Windows mobile, a couple of soft-resets per day are inevitable. RAM usage steadily increases throughout the day, and performance begins to suffer after heavy usage. The only solution to this is to perform a soft reset. It only takes a couple of minutes, but it's still a little irritation.
It's worth noting that the speed and stability of the device can be drastically improved by installing the latest software onto the device from the official HTC website.
The battery life on the device leaves something to be desired. It'll last for a day or two under light usage (the odd call and text here and there). As soon as you start using WiFi, browsing the internet or using the GPS receiver, the battery can be dead within 4 hours.
Windows Mobile isn't the easiest operating system to use. The Touch Flo 3D interface (as previously stated) increases user-friendliness of the device somewhat, but dropping back to Windows Mobile will be required at some point.
The camera is capable of taking printable photos in good lighting. In anything other than good lighting, the photos are blurred, full of noise, and the shutter lag becomes unbearable. In a dark-ish environment, you can expect up to 10 seconds for the auto-focus to sort itself out.
I wouldn't trade this device in for any other out there on the market right now. However, if you're not a fan of technology and want a straight forward device, this isn't the handset for you.
On the other hand, if you want a top-spec handset which does everything you'll ever need, look no further.
To sum up the pros and cons of the device:
- Stylish handset
- Impressive user interface
- Good quality camera (in the right lighting conditions)
- Poor battery life under heavy usage
- Camera only works in high lighting conditions
- Soft reset required a couple of times per day
