New Design House Targets Mobile Devices Only

It seems that the era of the mobile Web is here if we are to judge by the announcement of the first US web design house, Mobits.com, which only accepts jobs for developing mobile web sites! Their portfolio & demos show some nice screenshots of a number of mobile browsers being supported by the company and this begs the question: how does YOUR web site look like on a phone or a PDA? And if you do have a mobile site, is the user get redirected automatically to it?
