You know you've messed up big time when someone related to the development of one of the first graphical interfaces for computers thinks you've messed up. Usability expert Raluca Budiu has shared the common conclusion for many about Microsoft's upcoming Windows 8; it's definitely not as user-friendly as past versions. Quoting: 'The advantage of the overlaid menu is that it preserves context. Cognitively, there’s more of a burden when you have to switch context twice (desktop->start screen; start screen -> desktop). There are reasons to force users to switch contexts, especially in the tablet or phone environment, where screen real-estate is a lot more expensive and a menu is forced to use only part of the (already-small) screen. In that situation, a separate page makes better use of the small screen space. There are fewer reasons for a separate page on a desktop – the start menu is a cheaper interaction than the start page.'"
