I own an iPod Touch...it's a great device and all the millions of words that have been written around the web on it, I'm not going to add further on it except to say I think it's great...but!
iTunes sucks ! It's the worst bloated sluggish piece of desktop software I've seen in the last 5 years. When it updates itself it's patches are enormous, it loses it's connections to Apple's own 'Remote' applet on my Touch, it can't remember where I like to navigate to in the UI as any decent portal should...ugh the list goes on and and on.
Then there's the content and here the Register comes up trumps ! When the cheaptards continue to keep buying poorly-written, crash-prone, resource-hogging applications "...because they're only 59p !" where's the incentive for the gimps that knock these out to really innovate and take this platform to another new level ?
