Re: Is the iPad Mini a good device? I'm thinking of buying one.
Don't get the legacy Mini, get at least a Mini 2 if available, or better yet a 3.
I recently traded my original Mini 16 gig WiFi back to Apple for $75, picked up a refurbished Air 32 gig WiFi for $389 minus the trade. I'm a big fan of buying the almost next and best thing, and would only buy refurbished from Apple as it gets a new screen and battery as well as one year Apple warranty.
The Air is much, much faster and solved all the lagginess the Mini was starting to exhibit, Safari crashing, etc.... The faster processor in the Mini 3 or larger Air or Air 2 will see you thru a couple of Apple upgrades thru iOS 9 and beyond.
As well, the Air form factor is only a bit heavier then the Mini, I only notice the add'l size and weight when holding with one hand and reading. Retina IS an improvement and I like the larger 10" tablet keyboard, finding it more accurate when typing. As well, when surfing the web, pressing on links is more accurate on the larger screen.
