honestly, a 32" 1080p is a waste of money. unless you sit really close to it you wont notice the difference with such a small panel. if you are sitting that close then its horribly bad for your eyes anyway.
im not doggin 32" 720p tvs because i have a 32" samsung as secondary monitor for movies and such.
back on topic:
i dont know how long you could go with using a tv as a monitor because of its lower resolutions. its kind of a strain on the eyes especially if you are doing any type of work involving spreadsheets or word i would think.
i currently use a 20" Dell Ultrasharp as primary monitor for work and TV as media so that is a suggestion.
It's not a waste of money to ME, I am not dishing out 1500$ for a 30" monitor that I can never have a secondary use for.
I don't want a 20" that is way too small for gaming/movies, now answer the original question please.
To clear anything up, I use my laptop pretty much for everything else.
