I use a workstation so I find little in this update "exciting". I don't use a time capsule so the backup facilities are irrelevant. There is a lot of eye-candy. I certainly do not wish to have an itunes account to install software. I'm not a kid!! That may be fair enough for the IOS as it is a relatively new operating system.
I am also concerned that Lion will report back to Apple what software i have on my machine and that is frankly none of their business.
Apple also censors software it doesn't "approve" off so this update will impinge on my freedom.
I imagine when it is released someone will provide a jailbreak type program so that any software can be installed.
I would be excited if it could turn my ben-q monitor into a touch screen, or if i had a laptop turn the screen into a touch screen, but on the other hand i am quite happy using a mouse and keyboard.
