I am thinking waiting for Froyo is a good bet. But then I was also thinking that the very latest phones from HTC, and the Samsung, would likely be upgraded pretty quickly. But, I'm hanging in there.
Regarding memory: Coming from a WinMo background, that brings my nervousness about memory. Of course on that OS, even apps that install to SD use some of the main memory, and ultimately it becomes a problem.
So, do we know that being able to install to SD really gives us relatively unlimited memory real estate? Or would we ultimately run into a limitation of the main memory?
I do tend to install a lot of apps. Why else want a Smart Phone?
