I'm a longtime lurker, so I'm quite familiar with every tiny little aspect of updates or no updates and hardware specs of the MBA vs the Sony Vaio Z. Way back when the updates of the Macbook Pros were announced someone said people would now rush over to Sony for a new Vaio Z. - So, has anybody done this and can tell of the experience? I'm looking for the non-technical stuff. The things you rarely read in quick reviews. Yes, I know by numbers the Vaio Z is way in front. This I can find online easy enough. What I would like to read is long-time experience (say, upwards a week for each ;-) ), and what differences you found between the Vaio Z and the MBA. I'm looking for useability. Reviews say the screen backside of the Vaio Z feels flimsy and bends, and the handrest and underside feels like plain plastic. Is this true, especially compared to the MBA? What else is there: Fan noise. Ergonometry (I very much like the tapered design so the handrest ist so very low, and though I haven't tried the Vaio Z yet it looks plain old brick-y and thus very uncomfortably). The difference the trackpad makes. The difference the screen resolution really makes. Everything you can come up with.
