Sites not optimized for the mobile

Came across this article. The article says that more than 5% of hits are from mobile users. That makes it all the more imperative that websites are made mobile aware and adapt to the unique demands of the mobile phone.

What can be done to make the websites mobile aware? Are there tools out there that enable you to roll out a mobile enabled website hand in hand with a PC website? So you do not think about the mobile website being a whole new project?

I am a very avid surfer on my iPhone. Many websites that I visit are mobile versions and many aren’t. I surely do get turned off if the regular version does not perform as well on the iPhone.

I am sure that day is not far off when you would be designing primarily for the mobile and the PC website would be an after thought. What do you think?
