Must admit, I find the SP a fantastic piece of kit, fulfilling all my requirements and more (and I say that having been a diehard Apple user for the past 10+ years). Sure, there could be better aspects but then again, any piece of hardware could be improved. But for me, it is easily up to the task of desktop/laptop/tablet replacement. I love it and quite frankly don't care that it has come down in price. The only downside has been having to migrate my media to Windows (not found a quick and easy Aperture to Lightroom library transfer method yet) but that's no biggy.
Yea thats a bummer to have all the stuff and not be able to transfer it. I would suspect that isnt by accident but rather by design. Why make it easy for someone to leave your ecosystem? Then they are stuck paying for more overpriced hardware.
