Release Now?
Why not just release the damn things now with 2.1 or 2.2 and try to get some market share before they have to spend the next 5 years chasing Apple. As long as the OS can be patched to version 3 when it's released there should be no problem.
I know people that are looking for these now and if the delays keep going they will just end up buying an iPad before the end of the year.
