The inclusion of a new all-in-one desktop computer in Lenovo's Live Quarterly Update has prompted the company to come clean about the first of its new Edge family. With up to quad-core Intel Core i7 configurations available and at just 3.18-inches thick including the frame stand at the rear (or 2.5-inches thin if you care not to consider such trifles), the ThinkCentre Edge 91z is a might more powerful and a good deal slimmer than an iMac or, perhaps more relevantly, the company's own ThinkCentre M70z. Lenovo's "Do Machine" has been earmarked for small businesses and users looking to save some table-top space, and will be available in a number of configurations.
