I was one who was incredulous that these weren't part of the original software, but now that we have them, I can honestly say my experience with a Blackberry (used until I got iPhone about 3 months ago) is now surpassed in every way I can think of. I can now type at least as fast, maybe faster, on iPhone, even with my Neanderthal thumbs.

And the iPhone's cut&paste functionality is easier to use and more powerful than BB's.
But recently I canceled my Mobile Me account, after the free trial, because SaiSuke (which is gorgeous) and SynchInABlink do the same job, through Gmail, for a one-time $15, compared to $100/year for MMe. Another post did say that Apple doesn't "get" the Cloud, and I think this $100 fee shows that. Between free Gmail/Yahoo/Hotmail, synching apps and so on, who needs Mobile Me? I'd actually like to know, does anyone really love it?
