The PC business model is a zombie right now. I work at a joint that rolled out about 12,000 PCs a year, every year. Since 2008? 2,000/year... mostly laptops to folks whose jobs have become more mobile.

ALL of the good customer facing people with companies that peddle PCs in my neck of the woods have either moved on to greener pastures or are holding out for retirement.

My guess is that in 2014, those 6+ year old PCs will start failing and be replaced with tablets for about 60% of the workers. I betcha that the rest will be PCs from no-frills vendors like Asus.

Big enterprises are very conscious of costs, and the "whale" of client-computing costs is that fat Microsoft EA that just gobbles up capital. That's a big cash flow to build a business case for an alternate product.
