Repair-It

Cause I know you guys are using them.

TinyVNC works pretty good, but crashes sometimes when connected to a Windows 8 machine running Real VNC. It hasn't been annoying enough for me to troubleshoot it. It can send special key presses as well as has an on-screen keyboard for things like the Windows key and Tab, which might be nice.

If you are looking to control Windows Media Center, use Ceton's My Media Center App. It has a built in remote which works well and you don't have to deal with all the VNC desktop BS.

If you find a better VNC application, let me know.

I feel like a VNC client on a smartphone is never the right answer to whatever you are trying to do. I don't know what you are trying to do, but I stand by my generalization.
