Lenovo X60 / X60s / X60 Tablet	light/compact Notebook	The VGA option rom can be replaced^[1] CPU Microcode: most devices work without it^[2]	Some default Wi-Fi Card are from Intel and require non-free firmware. If you buy the laptop second hand and have an intel card, replace it. Else glugglug already ships with the good cards.	The default non-free BIOS can be replaced with libreboot, trough very dangerous and very complicated ^[3]instructions. Else glugglug laptops ship already flashed, and once the non-free BIOS has been replaced, reflashing is way easier but still dangerous.^[4]	Trisquel 5.5 and newer Parabola	Easy to find second hand, but very complicated and risky install procedure Can be bought already liberated at glugglug
Lenovo T60 (with Intel GPU)	Notebook					Easy to find second hand
Apple MacBook 2,1 / MacBook 1,1	Notebook		The default Wi-Fi card is an Atheros chipset which works fully with the Linux-libre kernel.	The default non-free EFI firmware can be replaced with libreboot, trough a dangerous ^[5]procedure		Easy to find second hand

It can be replaced by:
- Coreboot code, with text mode graphics support
- SeaBIOS's option rom that gives VGA compatibility
Both are probably needed, and coreboot changes will land soon in Libreboot, at the time of writing(august 2014)
↑ Some of the impact of not updating the microcode can be found in intel's CPU erratas, like the Core solo/duo erratas. A good way to avoid the issues described there is to have a cpu that has the bus you care about fixed in hardware: The more recent batches you get, the more erratas are fixed
↑ There is a big risk of breaking the laptop: Some time ago, lots of users tried and broke it, they cound't buy the laptop already flashed, so they tried it. They broke it because the instructions to switch from the original BIOS to free BIOS replacements are complicated.
That's due to some restrictions of the original BIOS, which tries to prevent easy reflashing.
↑ Once the free BIOS replacement is flashed, reflashing is easy, but still dangerous: if the free BIOS replacement doesn't work, then the user has to disassemble the laptop and reflash with an external flash programmer to recover.
↑ If your macbook has the right flash chip, flashing it is easy, but still dangerous: if the free BIOS replacement doesn't work, then the user has to disassemble the laptop and reflash with an external flash programmer to recover.
