I have the Nexus 7 here and it's very nice. The Android OS is unlike any apple or other system but easy enough to get along with.
I use DropBox to sync with among other things but for us the Kindle Fire HD 7 actually gets more use because it can hook up to the HDTV and stream HD movies from Amazon. It's email is very good too.
My point is that you need to think about use. At no time did I ever think this will replace my laptop.

I am planning to purchase my first tablet and am considering either the Nexus 10 or the iPad 2 (the iPad 4th generation is too spendy for me right now). I like many of the features the Nexus 10 has like the display ppi, front-facing camera resolution, newer Bluetooth and NFC, GPS, etc., and of course the price. My dilemma is that I have an iMac desktop computer and an iPod Touch, so I am concerned about connectivity (or even if differences in OS's even matters). I would appreciate any recommendations for getting the best bang for the buck, and/or if I should wait for some changes in prices.
