You're contradicting yourself horribly. You say it's reliable yet you admit there are issues that require a factory reset which nobody in their right mind wants to do or should be EXPECTED to do with a supposed update.
I don't run into problems with roms or radios or bootloaders or recoveries or rom.zips because I use MD5 checksums also to verify integrity. At which point I move the file to the phone using a USB cable.
If I had a dollar for every post about how the OTA borked my SD card, pics, vids, etc I'd be a rich man. Look it up. And while you're at it, maybe you can tell us why people who were already on 2.2 for many months got it pushed to them again which REALLY caused major problems.
So "incorrect statement" was an incorrect statement. You talk like you're reading from a flowchart but you have no idea what users go through out here in the trenches. If you do, you choose to ignore it to preach the company line which in many cases is obvious BS.
