iPhone, for business users?
"at least in the iPhone's case - slowly establishing a firm challenge in the smart-phone market for business users"
Not likely. I don't know any self respecting business user who would rely on an iPhone to handle their business needs. Sure its great for farting applications and playing music, but have you every tried to type 30 emails an hour on a touch screen iPhone that doesn't even cut and paste? 'nuff said.
As for Eclipse, I've used it before and was not very impressed. Mind you that was four years ago so things may have changed. If it makes it easier for me to develop Blackberry apps though, I'll give it a go.
