Personally, I've got serious reservations about the long term viability of the keyboards on these (including the ones from last year). There's been a number of reports of people having problems with the keyboards starting to fail, and I know the one person we have in our department that has one also has intermittently had problems with her keyboard. Part of it just seems to be that they're exceptionally sensitive to any dust getting in, but they also seem to have some issues with failures, especially on things like the space bar. (All that on top of what quite frankly is a keyboard that has to be in the running for single worst keyboard ever created anyways.)
