Too big and clunky and... oh, not any more!
Having borrowed a Nintendo DS a while back, I thought it was too large, too clunky, too plasticky, the battery life was too short and the screens were too dim. Perfect fodder for a rant. Except that Nintendo have listened to its users and are launching the Nintendo DS Lite this month in Europe!! It's smaller, brighter and generally better in every single way. So consider this a rave (a good one). Highly recommended.
