Sony & Dell laptops take a lot more hammering, I had Sony one for 4 years over Uni, that got carted around everware, backwards and fowards to home every week, countless USA trips chucked in Over-head bins in airplaces, never missed a beat! HP laptops come across as has very fragile :-/
Send the Viao to a museum, as yours is a record breaker

As said, none of these companies make LCD panels, so they are equally robust. A cracked screen is always caused by distress. Nothing else.
Apart from Acer's, most unreliable I have come across is the P4 based Latitudes, such as the C640. You can guarantee they will be needing a new system board within warranty, and again shortly after.
Of all the ones I have personally owned, including work issued ones, the most impressive was my last Tosh (Sat Pro 2410). By the time I gave it to my best mate, it had fallen in the bath 3 or 4 times, been dropped off worktop several times, even been left on somebody's sunroof after a tech2 session when they drove off. OK,, the screen hinges had failed, the case looked battered, but the bloody thing wouldn't die. Still going strong now.
