Well.... The mini better have some better specs. I realize that iOS is highly optimized and does more with less hardware but 512 megs and a processor that was nearly 2 years old in the first was a let down for me...
I bought a Nexus 7 last week (my first Android device ever) and while iOS and iDevices are much more polished and the Apps on iPads are better, I'm really enjoying the freedom of Android. Being able to boot up uTorrent, download a file (not pirating, thx), unzip it in a real file manager, and then play it all without the need for my PC was pretty nice. Not relying on Dropbox or email to transfer files back and forth (non photos) was also great. I'm afraid that Apple lost my bucks on the Mini if this Nexus continues to impress (although I might spring for a mini for my daughter).
