Almost at the point of ordering this one. Couple of questions to owners of i may. 1. PIP functions, can this be done with ANY 2 inputs? or does it HAVE to be INPUT+TXT, OR INPUT+PC 2. I know the speakers are detachable, but I really dont need them. Are they any good, and do you reckon Id get a decent sale price? Does anyone sell this TV without Speakers for a lower price? Thanks in advance.
