A great product, lightweight good battery backup, very fast performance. But, do NOT buy. Cons: 1. Highly irritating: The screen is very glossy, to the extent of being irritating. Self-reflection is visible even inside room in CFL light. 2. Medium problem: Only two USB hubs sitting just next t each other. It's tough to use both simultaneously due to closeness and general bulkiness of pen-drives etc. 3. Minor issue: The microphone 3.5 mm jack-port is missing. Though the inbuilt mic is very good and suffices for skype calls etc.
