Recent notebooks incompatible with ubuntu?

view full story

http://askubuntu.com – I'm thinking about purchasing a laptop. Since without Linux it would be for me a worthless object, let me ask the following: Are there recent note- or ultrabooks that cannot support Ubuntu 12.10 installation? Are there notebooks that work considerably below the features they promise when one uses Ubuntu? (I post this question because I saw this post and fear not to buy a right product). (HowTos)
