what is the best ultrabook/ portable 13-15 inch windows 8 laptop for under $1000?
Depends what you want to do with the laptop. For high performance get one with lots of RAM. For storage and basic needs, get one with a high Hard Drive space. Most are sold with a 750GB-1TB hard drive.
Satellite forgot who makes it
ultrabooks are not high performance due to their lack of high processing power and dedicated VRAM but for anything basic there great I recommend the asus Taichi and the lenovo yoga
