I waited for the updated Mini and bought it first day available. I'm running into problems with practically every feature I was hoping to take advantage of with the Mini & Lion. - Remote screen sharing: It works, but very sporadic. Sometimes its fine, but usually it hangs up for 10 seconds at a time, then finally does what I said, then hangs for another 10 seconds. Totally unusable. Lion has a new virtual screen mode which works, sometimes, but has hung the mini I'm sharing into many times. I sometimes get a spinning wheel that never ends. Can't login, can't even get to any login screen. Have to hard poweroff. - Wake up on Wifi: This sounds great. Should be able to wake up a sleeping Mini by attempting to access some of its resources. Except that it doesn't work. Its been reported on the Apple website, several people have submitted a bug report. No response from Apple. - Highdef Netflix: I was hoping such a powerful machine would be able to smoothly view Netflix high def, but I still see choppiness in it. Not sure who's fault it is. I can watch other highdef content from VLC, Quicktime, even YouTube (flash) without problem, generally regardless of format. - Bluetooth mouse: I have a Microsoft bluetooth mouse which I've been using with an old white Macbook without trouble for a year. Now with the Mini and Lion, sometimes the mouse seems to lose its pairing. The Mini will says its offline, but sometimes it says its online but still won't work. Eventually I have to put the mouse in pair mode again, the Mini says its already paired, but if paired again it works fine again... until the next time it fails. I don't know if this is a Lion problem or Mini with its new bluetooth support. - Unrelated to the Mini, I've also tried using XCode in full screen mode on my Macbook Air. Usually works fine, but I've ended up with the system hung totally unresponsive, requiring poweroff reboot. After losing my work a couple of times I decided its not worth the risk and havent used fullscreen mode. Haven't had it lockup since. Anyone else having similar problems?
