At this point, I am considering upgrading my HD television set to a 52" Samsung flat screen. This would live in my living room, of course. But I may hold off on that purchase a few months; it seems like I am still recovering financially from not teaching summer school in 2008 (all the while spending money while in Stanford and Oxford). Plus, surely prices are due to come down in January.
In the meantime, I may get a smaller set (26"?) for the study upstairs. I'd connect this to a new PlayStation 3 and--perhaps--an Apple TV unit. The PlayStation would provide Blu-Ray capacity, and I'd move it downstairs when I upgrade the living room set.
Big plans, big bucks. But at least it's all getting cheaper!
