We've been pretty underwhelmed by the Lenovo IdeaPad S10 thus far, and the news that this machine runs particularly hot (and not in the good way!) isn't likely to win over too many, uh, fans. The keyboard itself gets pretty warm, with temperatures measured between 38 and 42°C (100.4 and 107.6°F). That slightly edges out tests performed on the Eee PC 900 (101°F / 38°C), and leaves your Cloudbook (83°F / 28°C) as cool as a cucumber. There's no word on the bottom side's heat signature, but with keys like this we aren't expecting good things.[Thanks, Patrick]
