Hi,
I would like to create a mobile version of the existing site (www.ochutnavac.cz) on specific URL (dont need detection of mobile browser) for example: www.m.site.com or www.site.com/mobile.
As far as responsive design vs device-specific pages, it's never good to get too locked in to any technology (Flash?) or methodology (table-based layouts?). Here's a very interesting article discussing that subject http://sixrevisions.com/mobile/responsive-web-design-not-the-future/
