Digital Post-it Notes with the MintPad

Guys that used to work for Iriver decided to come up with a small pocketable device that is actually a mix between Nintendo NS, an iPod and Post-it notes. How is that possible?  The MintPad, allows users to send a digital hand-written message to another person using the MintBlog feature. It also packs a 3-inch display, surfs the web via WiFi (802.11b/g), plays music and has 4GB of built-in memory. Not sure how useful it is but seeing the $156 price tag, that makes me think. Would it be worth paying, or should we wait for an iPod application to do that? [via Engadget]
