Dell has launched new versions of its XPS One all-in-one PCs with the XPS One 24 and XPS One 24 (PRODUCT)RED just announced for the UK.

Available with a £1399 "from" price, the updated design boasts "sleek, sculpted lines", a 24-inch, edge-to-edge 1080p HD display and what's said to be "premium" JBL dual stereo speakers and sub woofer.

As far as the Bono-backed charity angle goes, each purchase of an £1399 XPS One 24 (PRODUCT) RED system sees Dell donate a better-than-nothing $50 (£35) to the fund.

As well as the sexy-looking display, depending on options chosen, the XPS One 24 offers NVIDIA GeForce 9600M GT video graphics, a choice in Intel processors: Intel Core 2 Duo E7200 or Intel Core 2 Quad Q8200 quad core processor, 500GB hard drive and Blu-ray drive.

The machines are available in a choice of midnight grey, or pure white with the XPS One 24 (PRODUCT) RED version.
