Intel cut nose off to spite their face
Spin back almost 10 years, and Intel was probably the leading global ARM chip supplier, through the torrid history of Compaq and DEC and a lawsuit which ended up with Intel owning and flogging StongARM and XScale ARM chips - found in Compaq iPaq,s Dell AXIM;s, Sharp Zaurus, assorted Palm's, early Kindle's etc...
About a year before the iPhone came out, they flogged the ARM unit to Marvell for next to nothing (around $600m) to push laptop Atom down to mobile, and that has pretty much went largely no-where into mobile (I think there is a Motorola, Huawei and Vodafone handset running), with a small foothold in tablets (Samsung Tab 3, Tesco Hudl 2) - due to power consumption until relatively recently - though ARM have moved towards them with Big.Little on performance.
Somewhere between d'oh, and Schadenfreude.
