Apple MobileMe

Pros: The graphics on the box were nice. It was downhill from there.

Cons: Difficult to set up, forced me to switch browsers, then didn't do what I needed it to do. Adds an unnecessary layer of data. Customer-support doesn't even offer phone contact. Email only. Their policies are inflexible.

Summary: Had nothing but trouble with this. It was mispresented right off the bat, and I wasn't told about the free trial. After 2 hours of failed tech support by email, the rep admitted it wasn't doing what it should be doing. He gave up and offered to cancel the account and refund the money.
When my credit-card statement came, no refund. The Apple Store told me to take it up with Mobile Me. Mobile Me gave me a classic run-around and said they can't refund after all because the "activation key" was enabled through Apple. I ended up having to dispute the charge on my credit card.
To add insult, Apple's own tech-support person (on an unrelated matter) called Mobile Me a "disaster." Very honest and accurate. He told me about one minor setting change on my server that allowed my email to do what I needed it to do.
From a former newspaper consumer writer, I'd advise avoiding this product at all costs. The Iphone itself is great.
