Signed up at launch and so far VERY impressed. All those games for a flat 50Euro, it's a nobrainer really, but the added features like Autoupdate is really good, no more having to patch games when you want to play them, the PS3 turns on every night checks for updates, downloads, installs them, and then turns off again.
The games is the real seller for me, 4Euro for 4 games every month, games that I may not have otherwise looked at is really cool. I also like the 1hr trial of all PSN content, no need for specific demos, if I like the game, I can buy it at discount and unlock it.
Sweet...
