And FYI im not sure you're informed enough to comment since there are no 3G owners "happily fast switching apps" since fast app switching is part of multitasking which, as is well publicised, you dont get in ios4 on the 3G.
You do if you jailbreak it; the jailbreak process has the option to enable the 3GS-only functionality like multitasking and wallpapers.
I restored my 3G to a fresh install of 4.0.1 and skipped restoring from backup (I put specific files back by hand over afc2 afterward), jailbroke and enabled multitasking, and everything works fine for me, so mileage really does vary substantially between users - even with multitasking and the other features the 3G is supposed to not have enough memory for, it works fine for me (and I have a bunch of mobilesubstrate addons installed which eat up even more of the limited ram)
