Just got mine from Amazon, and I didn´t even realize it has 32gb storage instead of just 16gb, because 255€ was the cheapest option. I´m so used to 100€ price jumps for double storage in the iOS universe...
One thing I started to notice after playing with it for a while is how much more this little device feels like a real computer compared to my iPad. Copy photos on there via USB? Just drag a folder via USB. Thank god I can finally forget about syncing pictures through iTunes. Install one of the dozens of emulators on there, right from the Play store? Here you go! I´m still amazed that this is even possible without any kind of hacking.
There´s also small details, like actually being able to see picture metadata, show how large it is, when it was taken etc. That is something that always bugged the hell out of me on iOS. The data is there - give me a option to view it! I can handle it. Android doesn´t treat me like a baby.
And this is just from playing with it for an hour, not even going into stuff like replaceable keyboards or widgets or stuff like that. I also really love the three button (back, home, multitasking) - no more annoying home-button pushes or weird four-finger swipes. Switching in and out of apps or between them works much faster than on my old Mini.
I also really love the form factor - it feels like a super-large smartphone, which is actually what wanted all along, less like a small magazine, more like a big softcover. The soft back is also fantastic as well - I never liked the cold metal back of my iPad Mini, that scratches as soon as you look at it and slides all over the place because it has basically no grip.
I kinda regret never giving Android a chance earlier, but then again, the new Nexus 7 (and upcoming KitKat) seems like the perfect time to make the jump.
