The ability, or rather art, of being able to be in bed, pyjamas on (or off, if that's your style), mug of tea in your hand, cuddled up all warm and snug, whilst being able to listen to their adoring lecturers waffle on in class about particle physics or some jazz like that.
Granted, although there isn't a University of iTunes per se, iTunes U is beginning to really shine. The idea is to open up the availability of lectures to as many people as possible, if not everybody. Not everyone can make it to a lecture due to illness, disability, or being severely hungover (although, some would claim that to be a disability in itself), so having on-demand access to your education is a vital part of university. Obviously.
Even the lesser-cool yet higher-respected universities, who have recently come fourth and fifth out of the world's top universities, the University of Cambridge and the University of Oxford, collectively known as "Oxbridge", have put up lectures on iTunes for the
lazier less rich pompous gits advancement of student's education.
There are more universities currently throwing out iTunes content there to shake a stick at, more topics than your mind could ever conceive, and more videos and audio on-demand and available when you'd want it. Now, I hate iTunes with a passion, but if you don't have an iPod and have no actual need for iTunes, I'd still download it anyway just to get your hands on some of these virtual lectures. Take a look:
(FYI: this back-end editor will be the death of me.)
Not every university is on iTunes U, but a quick search on Google will give you a good idea if your institute has anything available, and in some instances "lay-downloads" of podcasts in MP3 format are available from some still. I'll be falling to a blissful sleep (induced with a mass of sleeping pills and a down of scotch) listening to Dr. Lee's Anglo-Saxon Tour of the British Museum. Ahhhhh, this is what university is all about.
