Another Android fanboy. Paid? Or confused?
Please. I have a Galaxy Fit, 128mb internal memory, 256mb RAM, 512mhz cpu. I loaded with with heavy widgets (Beautiful Widgets), a launcher (Holo launcher), icons (minimal ui), a heavy third party sms app (handcent) and a heavy keyboard (swiftkey). Doesn't freeze or lag. Loading times can be slow for sending mass sms or opening large ones with attached MMS though. If your claims were true, I won't use that phone to begin with, considering that phone contains my work sim card, and I work in a hospital, where lives are at stake. And that phone is reliable in stability and not freezing.
Any dev you'd talk to knows that Android is coded to manage memory itself, and is basically running the equivalent of Windows Superfetch.
Your phone NEEDING task killers is your own fault. It's like addiction. Using task killers breaks the Android pattern learning function, in such a way that over time it fails to manage apps properly and leading to freezing. Just like how a meth addict ceases to function properly during withdrawal and needs a good cleansing, your phone fails to function properly when a task killer is withheld and thus need a reset to function properly again. But the sickness will come back if again exposed to the drug, in this case a task killer.
I've already seen a similar case to your experiences a year or two ago here in this forum, where his high end phone will freeze if task killers aren't used. After a long thread of convincing him to reset and stop using a task killer, he came back a few weeks later and said that setting up his device to what it was before except for the task killer, and he says the freezes haven't come back.
I also went through the task killer myth, and experienced freezes and the lot back in my GB days, and have personally experienced disproving the task killer myth as well.
None of us here are paid Google advertisers. We are just advanced enough to know that what you preach is false.
If you dislike Android, then leave. As it is, you are like someone running across streets telling everyone you can fly, and everyone who says you can't is lying and paid to say you can't, when even your mother knows you're just hallucinating.
