They say that, but it's just bs to cover the iPhone's deficiencies. The real reason they like it is that it's so simple to use. They'll never like anything more advanced unless Apple first tells them it's easy, and then they'll actually spend some time trying to learn new concepts. With anything else, they'll approach it with a negative attitude and bash it when everything isn't immediately obvious.

To be fair, s60 actually is a bit difficult sometimes, but Maemo sure isn't. That's what's so great about it. Almost as easy to learn as iPhone OS, faster to use/customize, and the advanced stuff is hidden so lightly that power users feel right at home.
