Since the Air is out I expect iPad 4 refurb prices to drop on Apple's website pretty soon, or at least 3rd party sellers will probably start reducing the price. I've currently got an iPad 3 which isn't quite dead yet - just a little slow - but it is bothering me that I only got it ~6 months ago and it's already almost obsolete. Does it make sense to upgrade to the iPad 4 for a speed boost, or get the iPad Mini Retina instead? My biggest concern with the iPad 4 is that it may be a slow dinosaur 6 months from now. Unfortunately the iPad Air is a bit too expensive for me which means the alternative is a Mini Retina. Then there's option 3; keep my iPad 3 for another year and wait for the iPad Pro/Maxi?
