Just noticed this topic.
The company you want is called HTC. Its a Taiwan company who don't just provide cutting-edge technology, they damn near live in the future.
Obviously something that browses the internet would have to be a phone, as it would require connection to some sort of network.
HTC latest two offerings are the HTC Universal and the HTC Wizard.
They are not marketed generally under the name HTC, you can get them as an i-mate, or with specific network providers who think up their own names.
Universal:

Wizard (I have this, and it rocks! IMO the greatest piece of tech ever created)

There ya go. Good luck. Hope you find what your looking for.
Some men see things as they are and ask why. I dream things that never were and ask why not?
