Best true business laptop on the market
I'm typing this from a Z30, having just retired my incredible Sony VPC Z1 after 3 years of excellent service. I *hate* carrying dongles. The Z30 is the only lightweight (1.2 kg / under 3 lb) laptop I could find that still has VGA for hooking up to corporate projectors and Ethernet for secure networks that don't allow wireless. I laugh every time I see bozos with Apple notebooks who can't hook up.
The screen resolution made me hesitate as I was accustomed to the Sony's HD. But in actual use on the small 13" screen, I'm not noticing much difference. Plus, with the optional and surprisingly cheap dynadock, I hook up to two 24" monitors at my desk, with the laptop's panel as a third screen.
