Initially the software (latest VAIO and with heaps of RAM) made my laptop hang, but I rebooted and closed everything else, and it was ok after that.

It's obviously a very new system and there is very little on it so far (only one baroque opera, by an entirely obscure composer).  However, the prices aren't bad to download the operas which are on the system - around 4 or 5 euros for TRISTAN & ISOLDE or FIDELIO, and compare exceptionally well with purchasing them on DVD.  This is especially valuable to me, as I don't have a source of high-end classical audio or dvd near me...  (lots of pirate stuff and back-catalogue - but nowhere to get latest releases).

I've joined-up, and it will be interesting to see if it delivers everything it promises is still to come?

The danger will be if it continues addressing only the "classical favourites" market (rather like an online clone of "Mezzo") - it certainly seems to be shaping that way, pushing Carmen and La Traviata.  Let's hope they broaden out from this.
