When Hewlett Packard restructured its notebook range earlier this year it came up with three groupings. So far, we have reviewed one notebook from the Balanced Mobility range (the 6715b) and one from the Performance range (the 8710p). Now it's the turn of the Ultra Light range, which starts at around £950 (ex. VAT). For this review, we've chosen a model that costs just over a thousand pounds: the HP Compaq 2710p, a convertible Tablet PC.
