I'm sorry but Apple better start thinking about getting a larger screen iPhone out there. Demand is clearly there, and the Apple's ecosystem is second to none, but...
I stopped by my nearest Best Buy to see what the big deal is about the Galaxy S4 and I must say that Android and that humongous screen are compelling as hell. If Apple didn't have me in ecosystem lockdown (2 iPads, 3 iPod Touches, 27 in iMac, 17 in MBP, 2 Apple TVs), I would have jumped at one of those in a sec.
I see why people like Android, I just don't know the (uniquely personal) cons until I take the plunge, and whether or not it's worth it to abandon the ecosystem, at least in the phone category. However, I consider myself an average consumer and I think that at first glance Android is a perfectly capable and viable alternative to iOS.
But I'm not leaving OSX, or Apple's laptop/desktop hardware. I give Apple until December (when my contract ends) to come up with something, or I'm taking a break from iPhone for a couple.
