Having had a look at the HP site, click here, I'd not say there is a flaw - it seems pretty good value for the money but has a few shortcomings:
The ram comes as 2x256 which will mean that if you want to add more, you have to discard one of these modules.
The hard disk is 4200 rpm - the lower rating.
On the plus side, it weighs in at less than 3kg :-)
It's good for the money but I'm sure other forum members know better options.
