There seem to be so many caveats to choosing between choosing the two. Obviously I want mine for both gaming and watching TV/movies. Using it for the PC would be a bonus, I think Echoes of Faydwer on a 46+in display would kick ass :)
The two I have in mind are an RCA 61in DLP tv (yes, RCA) and an Olevia 42in LCD. Given I currently have a 32in Sanyo, non-HD piece of crap, both would be a big upgrade but the RCA would be (as Mona would say) hooge!
But there doesn’t seem to be a decisive yay or nay for either, and each seems to have its own ‘fanbois and h8rs’.
