Acer has released a pair of low cost touch screen Windows 8 laptops in the Philippine market. Both laptops are 14-inch laptops with 4 GB of RAM and 500 GB hard drives. The lower cost of the two is priced at Php24,900 and is powered by an Intel Celeron 1007U processor. The more expensive of the pair is powered by a Intel Pentium 997 processor and priced at Php27,900. I suspect we will be seeing Intel Core i3 and i5 versions shortly.
These laptops weigh in at about 4.8 pounds, and would fall under the category of thin-and-light laptops.
I suspect in a matter of a year or so, all Windows laptops, except maybe the cheapest entry models, will be touch screen units.
