They're going to keep rolling out new models of iPads every year, or possibly less now. Some will be S upgrades like the 4, others will have drastic redesigns and new features. It's pretty obvious, unless you have scads of disposable income or enjoy signing your paychecks over to Apple, Inc., that you'll have to adopt one of the following strategies:
1. Use what you got until it no longer needs what you need it to do or breaks out of warranty;
2. Buy the newly discontinued model off of craigslist or the refurbished store for a tidy discount;
3. Buy the base wifi model and use better file management, cloud storage and possibly an LTE mifi if necessary (the more expensive the model, the bigger the resale loss);
4. Donate your 'old' model to a charity for a tax write off (?);
5. Any combination thereof (such as buying a refurbished 16gb iP3 for $378 and possibly selling it for $300 when the 5's come out, and then buying a refurbished iP4 for $378 again-actually, that doesn't sound too bad at all);
6. Or buy applecare plus and accidentally run your iPad over with a cement truck as soon as you find out your local apple store is out of refurbished units of your same model. (KIDDING!)
This cutting edge is bleeding the green out of my wallet. Count me as a victim of upgrade fatigue with this last release. At least until they introduce a new model that literally blows my socks off. Hopefully, that will happen by next April.
