Surprised these have not been mentioned yet (warning, hideous amounts of money!):

aside from the interesting name 😯 they offer some truly lovely cases, but you do have to be careful as they can be bulky.
I still have one of thiers from my original iPod circa 2002, and it is still doing great service.
For the iPad I got the leather agenda 2, in custom colours, and it’s great. I had a macally one which appears a great combo of price and functionality, but the tab broke off after a month, and it did it again on the replacement. Avoid.
I also had a belkin one that had a handstrap on the back, quite handy for reading in bed, but a bit bulky and hideous.
Love my vaja. ahem. 😉
