I have had Igloo for a few months, and find the whole experience slooow. When navigating either the EPG or the pop-up guide, button presses get missed, and then it will scroll up/down 2 rows instead of one as it tries to catch up. It takes several minutes to boot and as mentioned always turns itself off every night (and this is a MAJOR WAF issue).
Also, twice now it has managed to lose ALL the EPG data, and I had to reset the box to get it to come back.
The only reason I am keeping it is to use it as an external tuner into my HTPC (running Windows 7 Media Center).
