[citation][nom]dalethepcman[/nom]Congratulations Apple, you just convinced 3 million people to pay $30 for a service pack AGAIN!You added text messaging, a notification interface stolen from Google, iCloud (wheee), and a default security setting that only lets you install applications from iTunes to a desktop computer.All hail the greatest update ever..[/citation]
Having "Gatekeeper" disabled by default would make it utterly useless, because the normal dimwit user would never activate it in the first place and developers would probably not even bother with registering and signing their apps.
The default setting allows apps from any source as long as they are signed by registered developers. That, along with a daily check for blacklisted developers, is a nice step forward in security.
Paying 20 bucks for a few new features, including system wide voice dictation (!!!!!!!!), is a much better deal than paying Microsoft 100 bucks for the privilege of dealing with Metro.
(Actually sounds like a good deal, if the voice recognition works properly.)
