BlackBerry 10 OS

Pros: - Gestures are fun to use
- "peek" and swipe to unlock can be quite efficient
- Refreshing
- Hub has promise, but I miss full fledge gmail app
- More polished at launch than Windows Phone 7 was
- Keyboard is fairly good, not "best" but is good

Cons: - Gestures not universal, should be able to swipe to go back
- Too many steps for simple tasks (multi-delete, add account)
- Long one-way streets in hub and settings
- Lag
- APPS!
- Lock screen notifications are useless
- Cascades are not useful

Summary: All in all, BB 10 is an interesting and refreshing OS to use. But BB didn't take the gesture integration far enough. The Nokia N9 and Meego integrated swiping gestures far more universally than BB 10.

The OS is fairly responsive, but somehow I thought the fluidity of the OS would be its strong point. But, compared to iOS, WP8, Android 4.2, this just isn't as responsive. Scrolling is choppy, flipping between homescreens doesn't keep up with quick swipes. Sure, it's great compared to BB7, but not quite there with the other big players.

Multi-tasking is going to be pretty useful on this eventually, however the cascade/tile things have very little usefulness at present yet take up a lot of space.

This is a great first step for BB, but lacks the polish that I'm hoping it will have a year from now. I'm thoroughly enjoying it, but when I have a busy day at the office, I pop my SIM into my Nexus 4 instead. When I'm getting lots of emails, dealing with the 'hub' just isn't very efficient. Not to mention that attendees/calendar invitations are not supported in BB 10 for google accounts.

Great OS for a casual user, but not ready for the power user yet.
