In fact, the last remaining Windows PC in my apartment (the rest are Linux now) is an old Toshiba Qosmio[0] behemoth from 2010 or so running Windows 7. I keep it around for some apps I use on occasion that don't run especially well on WINE. I'm not sure what I'll do when that thing finally dies.
I can't comment on their Windows targeted laptops, but this chromebook is my least regretted purchase so far.

It's sad because Toshiba was credited on the ACPI specification documents so how they messed things up so bad I don't know.
To this day, the Toshiba I own currently only works with Windows 7 and Linux. No support for any of the BSDs.
Of course, I did spend a couple hours after the first installation to uninstall bloatware, and upgrading the BIOS, and after a while I installed more RAM… but after that it was a good ultrabook which even had a physical Ethernet port!
I also liked the fact that it was 1.4 kg IIRC, and with a battery that lasted all day so I didn't have to bring my charger on the go.
Granted most Japanese makers are horrible on the software side, but Toshiba felt specially handicaped in my opinion.
