I recently rejected my Sony Vaio and got Lenovo Yoga and I am pretty impressed by the overall quality and smoothness of the laptop.
Its really is a beautifukk machine and I would say that Lenovo products are a real bang for your buck, My friend has used a Lenovo laptop for around seven years with out even reformatting it once and still he never faced any problem with it.
Guys lenovo laptops are very reasonably priced and has better quality than the competition, Yoga is really a beautifull and powerfull machine.
