Well, hopefully if you're 'investing' in Apple, you're actually paying attention to the products, user-experience, changes in how Apple is running the business, etc. and not just 'playing the markets.' And, if you've been paying attention for long, you'll recognize the difference. I guess we can debate about whether it's a change for the positive or not. I say not. BTW, I was never in (though I recommended buying AAPL back in the mid-90s, not so much anymore, though you're probably fine for a few years yet.)
Yes, but they run Android.** Water resistance might be nice, but isn't that already kind of in place (at least rumored for the 7). afaik, there are trade-offs with quick-charge. Wireless charging is irrelevant. Dual speakers, seriously? (You're not one of those annoying people who play music on the train through your phone, right?)
** My point being that I've nearly always been able to build up a PC with better specs than the Macs I've purchased. And, I have the skills to do so (did it for years for work). But, I run Macs because of OS X, not some specs. I should probably mess with Android again one of these days, but every time I have, it pretty much sucks.
The OS is fragmented. If I pick up say, an LG, I would have a horrendous experience. Same with an ASUS Zenfone. Pure Android has been great to me for years and I highly suggest it.
