In the last two days, we’ve seen HP and Acer announce all new ultra-thin low-cost laptops. And not to be left out of the slimming competition, Lenovo has just come out with its U350. The 13.3in laptop will sit firmly between the US$700 to US$800 price range, but is less than an inch thick. It comes with Windows Vista, can cram up to 8GB of RAM into its skinny shell and will be available with an SSD option too. So who do you think will be next to oust an ultra-slim? LG? Samsung? BenQ?
