A friend of mine bought a HTC Desire Z (of which the G2 is a variant) but while it is supposed to be in the powerhouse department (at the opposite end of the spectrum of a Galaxy Spica) its UI feels jerky, laggy and generally unwilling to respond to some user actions. My friend, despite being on the geeky side, seems not to notice it and because he seems to enjoy the phone I'm reluctant to make him notice and ruin its experience. Certainly this has to come from the fact he comes from a feature phone, so that phone is definitely an improvement.
I don't disagree with your observations about a pre-Gingerbread device, however it is remarkable how much 2.3 has improved. It is very competitive with the iPhone now from a spit and polish perspective, even on older hardware. So imagine the shine on a device like an upcoming Galaxy S II.
This segues to arguments that have a freshness dating. Android used to have crap hardware (the G1 was junk). Now it has amazing hardware. Android used to have no apps. Now it has an unbelievable number of apps, and almost all of the top tier apps. Android used to be a duct-tape clunky mess. Now (Gingerbread) it's a completely different beast: It is actually a loveable operating system.
So if Android made most of its gains when it was a shadow of what it is now, what are the detractors left with?
