I picked up one of these yesterday and I just love the Google experience. Android apps have come a long way in the last few months and I think Holo standardization has been a big part of it. Lots of good looking apps and widgets that I'm enjoying. Unfortunately, there are still a few apps that don't work on tablets, and I'll still use my original iPad for following my ESPN Fantasy Football league (their iPad app is almost better than the desktop website) and Facebook (still terrible on Android). But it's great to have a real, fast web browser (loading The Verge: <1 second on Nexus 7, 5 seconds on iPad 1) that can handle multiple tabs at once (even my friend with a new iPad complains about this issue in Safari) - the main consumer reason I picked up the tablet. It's nice to have intents and easy sharing. And honestly, I had so many force closes on my iPad apps that I just got used to them.
When I first started playing with it, I was wondering if I had made a mistake picking up a Nexus 7 - it just felt like a bigger version of my phone (Galaxy Nexus). But then I went to the core apps like Gmail and Calendar, which are designed specifically for tablets and really improve on the phone offerings. I like having a lot of screen space for my widgets, too - it almost feels cramped going back to my phone, where I have to scroll to see all of the widgets I have on one tablet screen.
The one thing I'm not sure on is if I like the 7" form factor. I don't bring the tablet out of the house, so the 10" size of the iPad was fine with me. But at $200, I can live with it. I do really like the pure Google experience and I'm not sure I would have ponied up more dollars for a bigger screen and older OS. The voice recognition is just really good on Jelly Bean - this is really a powerful OS. My Galaxy Nexus got rolled up to Jelly Bean the day before I got the Nexus 7, so it really feels like I am using the best and newest mobile software out there.
When people ask me whether to go iOS or Android, I've been convincing them to stay with what they know ecosystem-wise: if you've got an iPhone, get an iPad, and vice-versa; if they're excited about an iPhone, get an iPhone. I wouldn't have been caught dead with an Android tablet a year ago. But it's getting to the point where I think there are some really compelling reasons to try out an Android tablet or phone: widgets / live tiles (especially for weather / calendar / to-do lists / power controls), smoother sharing between apps, Google Maps, and a better web browsing experience.
Also, there's a
25c app promotion going on over the next 5 days at Google Play.
