I commute a lot, mostly on the train, which explains why my need for entertainment on-the-go is a little bit on the extreme. Over years I used all kind of portable devices, from actual paper books (remember those?) to the wide range of media players and e-readers. Couple weeks ago I got a budget approved to get a new toy and was really torn between [Ipod Touch](http://www.apple.com/ipodtouch/) and [Zune HD](http://www.zune.net/en-us/products/zunehd/default.htm).
