In recent months, we've seen both Lenovo and Acer push out rather stylish all-in-one PCs. Clearly, both firms are hot to trot for the form factor, with DigiTimes reporting that the duo has big plans for future expansion in the area. Specifically, Lenovo is rumored to launch an entry-level 20-inch unit (C300) next month, a C100 and quad-core B500 in August and an ultrathin A300 variant in October. Meanwhile, Acer is said to be preparing an 18.5-inch model produced by Wistron, though there's no indication if it's actually different from that
