Keep in mind that Sony is not the bottom in notebook reliability (not having a problem at all) --they rank #3 or #4 overall with Apple #1.
The problem arrises that if you do need service (and especially if you are not a techie and may need to call for even minor assistance) Sony service was rated last against major US notebook and desktop companies -- a full point below the Dell/Toshiba/HP/Compaq companies above them (Apple is #1 in service also).
So, if you want a ultralight notebook Sony excels in those but be aware that the service issue looms if you don't have someone to support you with issues otherwise.
You are paying alot for the Panasonic Toughbook if you are not in Iraq on the battlefield or using it on a construction site or other rough use here.
IBM notebooks have very solid cases, self-parking hard drives and they are #2 in service to Apple -- these are pricier than other brands but much less than a Panasonic Toughbook ...
I need a very light weight computer as I travel a great deal. Though I would love to go with IBM I want something with an internal optical drive. I think I am now between and Panasonic Toughbook Y2 and a Sony Vaio,but not sure which way to go. Especially concerned about poor support problems I have heard about for the Vaio.
Any insight would be greatly appreciated!
