I love my Lumia 900, and would never give it up for an Android phone, but I was playing with my friends Nexus 7 the other day, and it is a pretty nice device. I already have an iPad and a HP Touchpad, but I don't really like the 10 inch tablets. I mainly want something to read on, and I find them too hard to hold for extended periods of time. I was planning on just buying a kindle, but for a little more I could get a nexus 7, and be able to read and do more. Plus, I'm a tech geek, and it would give me the ability to play with all the new android developments.
I have been trying out a Galaxy Nexus with Jellybean (GSM unlocked from the Google Play store).
I would NEVER get the Nexus 7. I'm glad I have this phone so I can keep up with what's going on with Android, but all the software fragmentation drives me nuts. I could probably get some help over at Android Central for some of my issues, but I really don't care enough to go ask, and from previous experiences asking Android questions, the users over ther are not as nice and easy-going as WP users.
Ok... So here's why I hate and like my Nexus:
-Consistent Force Closes in various apps
-I can't use my Zune Pass
-I hate being scared to install free apps because of possible malware (even when browsing the Play store)
-Everything seems VERY fragmented, even built in functionality seems like it was created in pieces (some of that seems fixed with Jellybean, mainly the camera to photo viewing/sharing)
-People complain about WP's background tasks... But at least I know what I'm getting with WP background tasks. I never know what's going on with things in the background of Android, or if an app will randomly quit when I'm not using it. For example: If I'm using Google's "Listen" app to listen podcasts and I close it to running in the background, sometimes it will randomly completely close and I'll have to re-launch the app to finish the podcast.
-Podcasts... Google's "Listen" app is HORRIBLE. I rarely ever downloads a podcast or auto refreshes the feeds.
-The face unlock rarely works. It's a useless novelty.
-I hate the Gallery picture/video viewer. Hitting the back button I never know if it is going to take me back to the browser window I came from, or to some random picture I had open at some point.
-Battery life sucks (I have to charge it daily.. or else..).
I'm sure there's more negatives.. The final negative thing I will say is that my wife and I have Kindle Fires. We stopped using them and they are pretty much just toddler game machines for the kids now. They are even more buggy, crazy and only have access to the Amazon store, not Google Play.
The positives: The screen is amazing. It makes me sad to still see the 480 x 800 when I use my Omnia or Titan. There are more apps available, but like I said.. I'm scared to poke around the app store too much because of malware.
Hope that helps. It was more of a rant than anything, but I don't want to invest the time hacking and tinkering to make the Nexus work the way I want it.
