I posted here about chromebooks a while back and while that may still be the way to go, but as you folks suggested, I'm not sure they're right for my needs.
What I currently have: MacBook Pro 15" from late 2011. (quad core i7, Radeon 6750M) From memory it weighs about 2.7kg!
What I do on my laptop: Run linux, code (C, C++, Python, a few OpenCL extensions), write lab reports in LaTeX, and normal stuff (read fairly large PDFs, browse web, watch videos etc.).
The MBP is larger and heavier than I like to carry daily, in fact I tend to try and manage with my 7" tablet to avoid carrying it if I'm going to walking across campus a couple of times a day. It is certainly not an efficient way of going about things.
So criteria for a new laptop would be: Small(ish) and light. 11-13" and as light as possible. Easy to get linux running on (in my experience this is generally achieved by having intel hardware throughout (no discrete graphics)). Decent battery life (7+ hours browsing or coding), trackpad and keyboard that don't make me want to slowly stab every nearby radioactive source into my eyeballs. NO touchscreen - DO NOT WANT, just adds weight and munches battery as far as I'm concerned. Avoid the devil's resolution (1366x768) if possible, but I'm willing to compromise on a smaller panel.
Budget: As cheap as possible whilst fulfilling my major requirements; I don't need oodles of power (have the desktop under my name too.) I should think a pentium or i3 would be largely sufficient, as is 4GB of RAM, 2GB would probably do as I'm going to be using it in linux all the time. Lets say limit of £600 for now but as low as possible.
You're my only hope Hexus... well not quite but after two days of looking and not really seeing much that appeals I thought I'd ask people in the know. I'm expecting to have to compromise on a few criteria, so throw your ideas out there.
Many thanks,
Chris
