Hello all, I currently have an iPad 4th gen on ios 8.4.1. The tablet runs fine, and my uses are pretty limited. surfing the web in bed; using legal apps to search case law, statutes, etc. while waiting for hearings or depositions; watch videos while working out in my garage home-gym; using Bible apps and Pages to present lessons to our church's youth group, etc. I also have an iphone 6+ and a 13" rMBP that I use for any heavy lifting. Other than the uses above, the ipad is considered a "3rd device" if you will. Given the ipad air 2 offers (staples and the Target cartwheel app), I wanted to see what your opinion is on upgrading to an Air 2. Is it worth the upgrade, or will I really only be getting a lighter machine??? I have posted my ipad on craigslist as a feeler, and I've been getting consistent offers of $200 cash for the ipad 4. This would mean that I could effectively upgrade to an ipad air 2 for about $120-130. Thanks in advance.
