iPod touch with WiFi = Better learning experiences?

Looking at today's e-mail although the ALT-C 2007 conference is finished, well I am home as only a short hop to Derby, I thought this product release could not go unmentioned. The new range of iPods includes the iPod touch which is WiFi enabled and in view of the interesting points that Dylan Wiliam made during his keynote address (Link to page for link to talk not the 75Mb download!) the feasibility of multiple question answers onto web pages then aggregated during a class session become an immediate possibility.
Like the iPhone it looks to be based on the use of the Mac OSX operating system which will enable developers to create small apps for in class question feedback at the touch of an iPod. Is this the tool that will take the iPod a stage further?
As the owner of an iPod Photo I couldn't see a reason to upgrade to the iPod video the iPod touch is a different animal and if I can surf the web why not web based telephony and no need for the iPhone which would solve the European mess of which mobile phone company to collaborate with? I am sure there are even more possibilities. PS Thanks for a great conference it was my first but definitely won't be my last with best wishes to all especially other bloggers.
