I\'ve been meaning to use jQuery Mobile for a client project that is to go live in about 2 months (in the end of April) but I can\'t seem to find any roadmap for jQuery Mobi
In developing a client site with it, the answer is a solid "maybe". It does a lot of things right, and Alpha 3 is a huge improvement, but there are definitely bugs and missing features that make it difficult to work with and make some interactions currently impossible.
It's a great project, and has a ton of potential, but I'd carefully judge your client's needs. If the current limitations are not show-stoppers, it's tons of fun to use and greatly accelerates mobile development.
