Portable Monitors for MacBook Pro? I'm looking for a Portable Monitors for my macbook pro (possibily a 14'')
Do you happen to know some model that is working on a mac?

I found this one (ThinkVision LT1421) but it does not work completely.
Have you tried the latest DisplayLink manager software? It is a bit of a battery-guzzler and has some limitations r.e. 3D acceleration, but may be an improvement on the native OS X driver.
