R.I.P. the netbook. Acer (ASIYF.PK) and Asus, the last two major PC OEMs committed to building the cheap, no-frills notebooks, have said they'll stop making them in 2013. The evisceration of the netbook market at the hands of tablets has been a blow to both OEMs and to Intel's (INTC) Atom CPU business, which now has to depend on the mobile device and TV markets to make up lost volumes. One silver lining: notebook ASPs are rising as the low-end falls apart and consumers start buying touchscreen models.
