It's just as well that it's not realistic to take it very far as the battery wouldn't last that long anyway. It only managed to keep going for just over an hour when running the intensive Battery Eater test. It fared slightly better with the lighter reader test, but still only achieved around three hours.
It also looks like it was designed by a short-sighted engineer. The black plastic lid is speckled with small reflective bits -- which is presumably meant to look distinctive, but in reality just makes it look like it's covered in small particles of dust.
However, that's nothing compared to the greying beige plastic employed on the inside. Make no mistake, this is an ugly, plastic-looking brute.
Despite its large screen size, it only supports a maximum resolution of 1,440x900 pixels, which is a waste of the increased display space and means that you won't be able to view 1080p HD video at its full resolution.
The 7720 tries hard and it's a good performer when it comes to crunching numbers or the odd bit of gaming. However, it's a large, ugly beast destined to stay desk bound, but a reasonable choice if you don't have that many visitors and are happy to hide it away if anyone pops round.
