This is basically true. However, more and more apps are being released now that require Android 2.x or higher. WinAmp, Angry Birds, and other popular apps. While new owners will probably be able to find old "1.5/1.6" versions of apps for a couple of years yet, as a group we'll be left behind by the next generation of apps. This will happen eventually anyway, but an update to Froyo 2.2 will probably buy us another 1-2 years of new and updated apps.
