I will not go into too much technical detail at this point, the others have done already enough. Fast turn-on, damn good EPG / SFI, fast switching times and a chic design! Even Sky is working perfectly - However, one needs this, a S02 card and a Alphacrypt Light module for the CI slot.
The only drawback is what bothers me a bit that USB memory will only be accepted with FAT32 format - Here you are restricted. But otherwise I can highly recommend the unit!
