Couple things I noticed when using my Macs in general.
1. Pairing Apple remote requires you to log-in as administrator. Yeah, it sounds stupid. I was trying to pair my Apple remote with my iMac to no avail. After reading Apple's document closer, apparently you have to log-in as admin.
2. Screen sharing doesn't stream audio output to the connecting computer. This is a bummer. With Microsoft Remote Desktop, the sounds produced by the windows client is streamed to my connecting Mac. Sure there's a delay due to the network, but it is useful in certain situations. Not the case with screen sharing. Gosh, for once Microsoft did things better than Apple.
