Looking for a more powerful Acer Chromebook? It'll cost you -- the company announced today that its C720 Chromebook is getting a processor bump and a new price tag. $350 buys a notebook with a 4th generation Intel Core i3-4005U CPU clocked at 1.7GHz with a 32GB SSD, a modest bump from the 1.4GHz Celeron CPU, 16GB SSD and $200 starting price of the current model. Acer says the new CPU will give the machine a noticeable performance boost without affecting the 8.5 hour runtime consumers have come to expect from the laptop. Little else about the Chromeboook seems to have changed; its still available with 2GB or 4GB (in a $380 model) of RAM. Still, if you want to save some money with Acer's cheaper, slower laptop, buy now: the new models hit store shelves later this month.
