3rd gen iPad on its way out

I'm one of those that were slightly unfortunate to own the first retina iPad only to have it replaced with a more powerful one some half year or so later and now I see evidence that this 3rd generation device is on its way to total obsolescence. I've encountered two apps in two days that either won't run or won't perform very well in it - Photoshop Mix and the newly released Bioshock game. Sigh.

What am I to do when my iPad becomes truly obsolete? Do I get a new one or get a Mac instead? Either option involves heavy investment by my standards. :(
