I would like to know what kind of netbook/notebook you use when coding during long commutes etc.
I don't really know what to look for in such a notebook (optimal size? battery life? performance? optimal price?), so your advice would be much appreciated.
On the other hand, a larger screen makes it easier to see under stereotypically bad lighting conditions.
I found it much more difficult to concentrate on the train than in my nice quiet cubicle. Those suffering in open plan most likely would consider the worst train car ever to be blissful calm compared to "work". Just saying your needs for calm are hard to predict over the internet. I had to put on earbuds on the train, but I can see those used to a more abusive workplace might not be bothered by train and passenger noises at all.
Personally I always locked the thing up and was uncomfortable a couple times on commuter rail even when just going to the bathroom. So you might want to think about, if I fold this thing up can it fit in a giant coat pocket or something. Would you be comfortable taking this device to the bathroom with you, because you're probably going to have to, sooner or later. So smaller/lighter would be better.
It is really a hard tradeoff of screen size to portability if you don't need to worry about power. If you do need to worry about power then an Air if you want OSX. This is what I'd be eyeing for other OS's

Underclocking the CPU is said to improve battery life also.
Newer intel CPUs. DDR4 RAM, and SSDs use way less energy than their predecessors also. So there really isn't much room to get this wrong when purchasing a laptop.
That's what I've heard...
