Christmas holidays were long enough to spend some reasonable time with the family, short traveling (Tuscany is always beautiful) and even resting and playing with the iPhone.
I tried quite a few iPhone “native” applications, many seem to me to be mostly useless, but some are quite nice. iSMS is the extension to the Apple SMS client that we all wanted (the UI is OK and takes advantage of the UIKit, of course you don’t get the iChat-like layout). iPhysics is a great game, inspired by Crayon Physics, it takes advantage of the touch screen perfectly, it uses the accelerometer when needed and is also a fun game. Reminds me a lot of The Incredible Machine, but with a spin. If you have an iPhone, I strongly suggest it, there are already plenty of custom levels.
