Mike Bartlett has written a very personal update to the beta users of SKype 4.0. I like the tone and direction, as it shows under Josh Silverman Skype is actually listening to users (including bloggers.)
The comment about a compact mode was my initial reaction when Josh took me through the details a few weeks back. With smaller screen devices like Mac Book Air's and the UMPC's from Asus and HP all gaining momentum with the road warrior set, the Mac and Linux team's efforts at Skype will likely be as important.
Here's to hoping that all three platforms at some point begin to run in synergy with release dates and feature sets.
