A1: IR doesn't drain the battery as fast as the WiFi. You do notice the effect, though. Not too bad.
A2: The phone can sit on the table as much as 2.5 feet away. I usually just have it sitting about foot in front of me. When on the move, I put velcro on the back of my clipboard so I can "stick" my phone over my T|C.
For some reason, program transfer is much more finicky than web-browsing. I think the error-checking is much less robust in file transfers, so it is more likely to fail then when maintaining an internet connection. Not sure why.
