I would like to get your feedback about any of these machines if you have tested any of them by any chance. I myself enjoyed using the Vaio TT a lot and it felt very fast in doing everyday tasks. The screen is very crisp and it does not suffer any lines or light bleeding like the MBAs screen. In addition, the keyboard is dead silent compared to the Air's! Please keep your Vista sucks comments to yourself and try to judge these machines based on their performance, specs and looks and simply forget about the OS for now. I am kind of sick of waiting for a problem-free MBA screen so I might consider one of these machines (mainly the Vaio TT or Lenovo X200) to be my on the go machine since the OS isn't going to matter much on the go even though I would still prefer Mac OS any time. Thanks in advance for your feedback.
