I'm going to be spending heaps of time in the uni library soon and want a decent mobile computer.  Nothing to replace my desktop at home, just something for the road.  

I know netbooks are going out of fashion, but I feel tablets are still too much of a luxury item - and from what I hear, word processing is their Achilles' heel. 

But what should I look for in a netbook, in terms of processor, etc?  What should I avoid (e.g., are there any brands that just aren't up to par with others)? 

It would mostly be used for word processing, internetting, the occasional movie, etc. 

Many thanks in advance!
