I am downloading the CS5 Master collection at the mo...

Anybody already using it want to share your initial thoughts? I will give some feedback in the next few days.

Alright I have some feedback...

Not a huge fan of the new icons!
but across the board the improvements are great and the performance is rock solid.

CS3 to SC4 was impressive... CS5 has definitely made itself a worth while cost.

They've improved the installers as well so yeh... the only downer is the new icons, I think I can live with that!
