Software to share your 3G connection over wi-fi

For long time, the easiest solution to share your 3G connecion to laptop over wi-fi is the software "WMWifiRouter". We have tried version 0.89 and it has been working quite sactisfactory.
Unfortunately, due to the popularity and success, they no longer decided to make the software free. The current version, version 1.30 is now US$29.99. Does it worth the money? You make the call.

There is actually one simple and elegant solution.

Buy ASUS P835. It has built-in Wi-fi hotspot function. The picture says it all. It even has battery display and time of usage. Pictures courtesy of Ringhk.com (link)
As of early April 2009, ASUS P835 is around HK$3800 in Hong Kong (around US$490).
