I’m sure you’ve already heard everything there is to know about Apple’s new iPod Touch. The “iPhone-minus-phone” is a beauty, and boasts the same innovative touchscreen interface and wifi capability as the iPhone.
In theory, and only if the software/firmware allows, the hardware should allow the unit to make a fantastic PDA. Add an email client (far better than using webmail in Safari), calendaring functionality and a basic note-taking application and the usefulness of the unit increases exponentially. I’d be much happier taking this on holiday than my MacBook.
