I remember wandering around Vegas at last year's CES and Kevin and I took a stroll by the Vertu store. We admired their offerings, but in no way could have coughed up the $12k to buy one. Well it looks like we'd have to save a bit more to snag the highest-end BlackBerry device to fit our obession. It looks like the world's most expensive BlackBerry is a diamond encrusted Curve 8900 that rings in at $240k. Our good friend Al Sacco has all the details, so check out his blog for the full scoop. Even if you could afford this... would you really want to?
