The Acer Aspire One D255 packs a dual core Atom N550 running at 1.5GHz but is somewhat crippled by a GMA 3150 GPU. The D255 should last eight hours according to Acer. The 10.1-inch LED-backlit LCD sports a 1024×600 pixel format. I think we’re ready for a wee bit more pixels, say 1280×768 on these 10-inch displays. The dual core Aspire One D255 will be available in November for Â£279.99.
