The iPhone is a best-seller (despite AT&T). As a single phone, it is probably the dominant US-based mobile phone today.
If you haven't yet taken time to see what your winery Web site looks and feels like on an iPhone, please do (I'm sure at least one of your family or friends owns one). Some sites are truly hideous. Flash-based sites don't work at all.
This has been a public service announcement. Thank you.
PS - the Apple tablet computer (the iSlate?) appears to be coming soon.
PPS - Everflight does mobile winery Web sites.
