[Nexus 7 General] Verixx:
Having owned an iPad 1, iPad 2, and TouchPad, here's my take on the Nexus 7. The TouchPad is so bad (comparatively) I won't even mention it here.

My use case is probably unique - keep this in mind. I use it primarily as a utility device (taking notes, server administration via SSH, database management, etc.) and secondarily as a consumption device (reading, games and so on.)

Functionality and design:

As is the case with all Apple products (by design), if you're part of the Apple ecosystem, you get benefits by staying inside it. If I was an OSX or iOS fan, I'd have kept my iPads. The iPad is unquestioningly a great product. That said, I cannot stand iTunes on Windows. Android 4.0+ functionality is vastly superior to iOS at the cost of design consistency. Most Android UIs look like someone's Visual Basic homework project. With that in mind, it is easy to make up for poor style with Android customization. It's not so easy to fill in the gaps in functionality in iOS.

I went back and forth between jailbroken iOS (great design + enhanced functionality) and well-crafted Android styles (great functionality + enhanced design) and settled on Android while putting some work into the UI/UX side of things.

Form factor and style:

For utility, the 7" form factor is superior. Fits in a pocket, can be shuffled around without being scratched, good weight and fit for one hand, can be controlled one-handed in a pinch. All while being able to read and interact with everything easily and clearly (versus a phone.)

For media consumption, I can definitely see how the iPad 10" form factor and a better screen would be more suited to you if you reviewed/critiqued images, designed on the fly or focused on consuming media. If you're not doing these things, then I think you would be happy with the 7" form factor (or perhaps the upcoming iPad Mini) - I know I am. It works perfectly well for games and movies, and I have no complaints to speak of aside from the (fixable) nVidia software glitch with the smartdimmer. Especially enjoy reading on the N7 compared to the iPad. I find it far more comfortable. If you need to constantly read small text, then the iPad's screen would probably suit you better due to the higher DPI retina display, but it's absolutely doable on the N7.

The form factor and toned down style helps while using it in crowded environments and in certain workplace situations, without drawing unnecessary attention. You don't want to be that guy, and this helps.

Battery life:

I've had my iPad on - uncharged - for the last 5 weeks and it's at 50% battery. The standby time is outrageously good.

That said, my N7 has been on - uncharged - for the last 17 hours and it's at 97% (see attachment.) That ends up being about 23 days standby. Pretty good considering how much smaller the device is. Not as good as the iPad, but it doesn't need to be either.

General thoughts:

With Android 4.1 Jelly Bean, I feel that Android has finally caught up to the smooth iOS user experience. It now offers an on-par user experience and superior functionality.

Without regards to price, I looked between an iPad 3 and a Nexus 7, and chose the Nexus 7. But that decision will be ultimately depend on your personal preferences and use cases.

Hope this helps someone that might be on the fence!
