I only recently bought my first Android phone, an HTC One. Prior to this purchase, I've had jailbroken iPhones, an N900, an N9, a BB Z10, and a bunch of other, earlier feature phones. I have my One tweaked and modded with custom everything (all free/donation based from XDA): firmware, hboot, OS/ROM, kernel, recovery, etc., so I may not be an average user, but to the people on this forum, I did what you would probably do with a flagship Android device.

I sincerely miss the multitasking advantage of Maemo and Meego. I still use my N9 a lot, so I agree that Android lacks there. Also as far as UX/UI, I think that Android needs to figure out how to avoid using the upper screen edge as a touch target in single handed use. My 4.7 inch screen makes using this area a challenge, and something like a Sailfish-type pulley menu is badly needed to avoid hand shuffling when touching or swiping down from the top.

But as for most of the problems listed in the thread, I guess that Google has figured it out by now and/or that they mostly apply to those with older devices (I'm glad to have missed those days). My One doesn't slow down, it's the best looking, best display, best sounding, fastest phone I've ever had. The app quality and diversity are tremendous. Apple and Google are absolutely dominating the competition here, and it cannot be mentioned enough. The Android development community, like here, is amazing. There are a lot of people working on Android's stuff, and the update pace and quality is insane.

So here's hoping that all the bugs and limitations get worked out, but I, for one, feel spoiled by all the great tech we get to use and play with.
