More dishonest than pretending that an iPod shuffle, which has no screen (and at one time no buttons!) and is functionally tethered to a real PC, is some kind of entry-level computer/grand charitable effort by Apple to make a computer "for the rest of us"? Or that an iPod Touch, which is not significantly cheaper than many laptops, can substitute as a real computer for anybody with more than the most casual, consumption-driven computer needs? Calling it a "great device" for the things you listed is very, very generous. Acting as though a $300 laptop is not also a "great device" for those things is just ridiculous.
An iPod touch is a great device for editing documents, watching videos, or even creating videos.
