*There is a standard way to exit...it's called the home button. Really.
*There could be an option to unlock the homescreen orientation, but only you and a hand-full of people would probably notice. Really.
*MTP sucks...I'll give you that, though the monolithic data partition was the right thing to do. Something like Airdroid is probably the way to go. It's fast enough for most things over wifi, and if you use USB tethering with it, you can tranfer gigabytes in minutes. QtADB isn't bad either.
*I think I've only seen maps crash once. Ever. Honest.
*Given the amount of time Google has spent getting the Android pieces accepted into the mainline kernel source, I don't know how one could argue that they are pretending that Android isn't Linux.
*Unlocking and relocking the bootloader, and rooting is absolutely perfect on the Nexus. Period. I'd say it's probably half-hearted on non-Google devices because that process sometimes wipes the DRM keys and you have to either flash a custom ROM or modify some root files to get that functionality back. There's nothing Google can do about that though.
*It would be nice if Google would collaborate more with the community on merging patches and bug fixing, but I don't know that Android would survive solely as a community project. This industry is moving fast.
For myth 2, the A15 design is significantly faster than A9, which was a big step up from the A8's. In four years we've gone from A8 to A15. It's quite impressive to consider how fast the phones in our pockets have gotten is such a short time, and I think it's a little early to forecast the trend. For myth 3, the Qualcomm Krait design is pretty equal to the A15 reference platform, and it's using a very power-efficient asynchronous design. Big-little isn't necessary, it's a less-elegant design solution that ARM chose. I think by the holiday season, the market will be flooded with A15-based phones. I believe the Apple A6 is also an A15 reference CPU, since they don't have an architectural license like Qualcomm and Marvell.
The 11 is for people with the pride of a 10 and the pocketbook of an 8. -- R.B. Greenberg [referring to PDPs?]
