I am considering developing a mobile edition of a web site for an application, and I'm considering whether to revamp my existing site to work for mobile, or create separate web sites. It seems to me even though some tout the benefits of CSS's capabilities, separate web sites is the way to go. Although devices like the IPAD and other 10" devices can support a full screen view, handling support for a limited view for devices with a 4" or 7" screen is a good way to go?
Factoring in phones, tablets, notebooks, and other third party devices, do you think its possible to use the same site across web and mobile environments, or definitely consider a separate site?
