Might as well add another post for future readers!
I have an M35X. Support has been OK under warranty, as long as you don't consider continual repairs and not having your laptop for several weeks every few months an inconvenience. I have had a hard drive go bad and four, maybe five (I've lost track) motherboards replaced. FYI - support is the usual off shore "we don't care how upset you are, no, we won't cross ship" common corporate model of today.
There are issues with the design (as in the engineers or accountants screwed up) of these era units. As an example, the power connector on the mobo is a known defect (just search Ebay for "Toshiba power jack"). Instead of correcting the problem by re-engineering the power supply and/or connector (the actual fix is rather obvious simple and I'm sure every engineer, accountant, adn upper level manager at Toshiba Laptop knows what to do), Toshiba just replaces the mobo. Worse yet, they repair damaged mobos and send them back out - but unfortunately, the word "repair" is rather strong - since the Factory Authorized Service Center has typically had to re order up to three times to get a mobo that was not DOA. This is just one example of the known issues with these machines - there are others.
As the other poster noted, instead of doing something nice for their customers to whom they've sold improperly engineered machines, Toshiba adheres to the strict legal requirements of the warranty. The power supply issue, for example, could be reduced by a factor of 85% just by supplying an updated power supply unit with a re-engineered plug, but Toshiba goes with the "least cost" method, fixes the mobo, and hopes that your machine lasts until the warranty runs out so they are off the hook.
I did notice that on the lapto of a friend who bought a new Toshiba that the power connector has been reengineered. Unfortuately Toshiba has done this to reduce repair costs, not serve their customers better, as evidenced by their refusal to fix, vs. patch, the earlier problem.
I used to like Toshiba - but I will never buy another one of their products.
