You can complain to Google as much as you want, but the fact is at SOME point in the near future sites will migrate to flash 10.1 en mass. The problem will come sooner or later.

N900 is not getting flash 10.1 (if we were Nokia would have announced it with fanfare like QT). So if you NEED flash 10.1 access, then bite the bullet and get another phone (Droid prolly) - cause you will be waiting in vain otherwise.
