I'm looking for a TV 32-40 inches in size or so, but I'm wondering what level of functionality I should go for. Can people share insight into:
* USB connectivity - can I really just plug in an external HD and play movies/TV shows or show photos etc?
* Wifi connectivity - does this mean I can play directly off laptop? Use it as a computer monitor? Stream from my iPhone?
* Bluetooth - how common is this? The only function I can think of is pairing with my bluetooth noise-cancelling headphones. But I live as 1 person in a 1 bedroom apartment, so its not like whether the TV is on or not will affect others apart from me.
Of course, reliability and clear picture/sound are most important.
Recommendations on brands, price range all appreciated!
