I mean old fashioned reinvent the MAC...
You mean like that shiny new Mac Pro they announced at WWDC last month? The machine for a niche market that Apple recognizes is an important niche for them to hold on to? There were some complaints about the lack of upgradability (have to my their specialized parts if you want to do it yourself), but Apple is also trying out modular, external upgrades via Thunderbolt. This is actually an old idea getting a refresh with some new technology that might make it more marketable/effective. Apple has been selling a ton of non-self-upgradable laptops & desktops for years... Why would they stop now? Obviously this is something that most average consumers don't care about (hint: they want the things they pay for to "just work").
You can only re-invent the wheel so many different ways.... They're trying to come out with new and more innovative ideas. Their product suite grows more interconnected/interoperable with every new release. Honestly, they're doing a better job of this than Google or Microsoft at the moment.
