Here's another one to say bye bye to...
Sayonara, netbooks: Asus (and the rest) won't make any more in 2013 | Technology | guardian.co.uk
Thing is, I actually like netbooks and found a real use for them for work, travel and pleasure. I'm actually using a recently purchased 10 inch Lenovo S110 netbook running Linux Mint to write this post, and it's what I mainly use for work.
Ultrabooks like the MacBook Air are just too expensive for what they are.
Regular laptops might be OK, but IMO unnecessary weight and bulk to always carry around for my requirements and needs.
A tablet could be OK, but it must have a real physical keyboard, some means of angling the screen for when using it at a desk or table, proper office productivity software(Android is a bit of a fail so far in this respect), as well as a VGA video outlet for use in the classroom.
