I thought the multitasking thing might have been overblown, but it goes deeper than just apps reloading and it has truly ruined the operating system.
App updates (like when you go into google play and hit "Update 5" or whatever) stop in the background, even if the screen goes off. Airdroid stops transferring files. Forums like this in tapatalk take you back to the main screen if you do ANYTHING else. Web pages reload, so good luck following comment threads on this site because you'll be back to the top of the page.
There's just no memory left over thanks to sense. If I knew a hard date of Cyanogenmod or something I'd keep it, but 350 days later after I got my EVO 3D, there STILL isn't an AOSP build that works for it, so I can't rely on the community to fix HTC's problems (that is not knocking the community, I'm just saying I can't just wait for them to hopefully get around HTC's mess).
Maybe I'll hate the S3, but 20 days in and this phone just feels worse every day.
