MSI Megabook S270 and T2/Linux
The MSI Megabook S270 series was one of the first and tiniest AMD64 sub-notebook, featuing the AMD Turion64 processor.
Especially for the included features and size this laptop's price tag is rather low.
While the overall quality, especialyl of the slim, colorful and angle independent display and the case is quite good - the keyboard is rather under average.
While the bottom of the laptop stays rather cool, the top side - including the keyboard - becomes warmer and can be a little unpleaseant in hot summer months.
Notes
The laptop comes with an INPROCOMM (Linksys, Cisco) IPN 2220 wireless mini-PCI card for which no open source driver is available. At least running a 32-bit Linux flavour the Windows driver can be used with ndiswrapper and otherwise the card can be exchanged in favour of an Intel IPW2200 easily.
The ATi 200M chip initially lacked open source 3D support, but in the meantime latest X.org and Meas git:HEAD versions are said to driver the 3D engine mostly correctly.
Suspend to RAM just works.
