OK, been looking at a fiew day in-store.
SONY TZ31 is OFF the list due to keyboard wobbling/flex. Nasty and cheap feel. Poor show for a premium product. Nothing like the quality that went into the Magnesium alloy case of the Z600 series.
Acer Aspire One D is OFF the list due to very glossy reflective screen, and very poor (sticky) touchpad.
The MacBook Air is OFF the list due to the very glossy reflective screen. Idiots. With a matte screen it could be a winner. It needs a thinner bezel too. No need for that flying saucer look. Make it a bit smaller.
