[Johnnytundra]

Hello,
I need your guys advice...

I need a laptop and i have only 3 options because of marriott rewards points. They are the Sony Vaio E or T series, "Lenovo U510 thinkpad"or HP Envy/ Pavilion series.
Which one do you think would be best for quality, multitasking, durability, graphics, and processing speed. Any advice would be greatly appreciated.

Thank you,
