Re: Changes?
Updating the CP in place took a little less than half an hour.
Not new, but I'll mention that on my 1080p laptop, the start screen shows 5 rows of tiles, not the three rows shown in that graphic in the article which must have been snapshotted on a low res display. Makes a significant difference. Hopefully this will encourage OEMs to ditch those ancient 768 panels.
First thing I noticed yesterday was faster boot time, then improvement in dual monitor support, hot corners work better now (found them annoying in CP version), can drag metro apps from screen to screen.
UI for Visual Studio 2012 RC is more usable (colour icons etc.) good enough to go apart from the ALL CAPS MENU. Felt more comfortable immediately than the Beta.
Generally not much obvious change really apart from the fine detail though in sum this feels closer to a real product that that CP.
I mainly work with desktop apps, apart from cosmetics its pretty much same as Win 7 (though we are told the Aero chrome is to go by RC so more change to come before can really voice an opinion, no problems so far though).
Still no compelling Metro style apps as far as I've seen - Kindle app works but needs more options such as double page mode on widescreen display. Will be handy to have the option of Metro style apps that will work the same on laptop, desktop and tablet can imagine some will prove useful but examples so far seem lightweight. Even basics like standard camera and Photo apps still missing what I'd consider essential features.
