Kies 2 is a lot better
Kies 1 was a total pig: slow, buggy and lacking features. Kies 2 is a very different beast and, as far as phone management software goes, pretty good. There is even a version with a subset of features for Mac OS. Kudos to Samsung for dumping an exercise in XPS based frustration for something better.
Anyway, glad you're happy with your HTC Desire: choice is good.
