Any laptop will do the job. It is more important what budget do you have and what you will do with the media from your A6000.
If you do jpg only, belive me any laptop will do the job, if you shot in RAW or need some movie editing software a good laptop with more RAM and a good graphic card can be required. And the last question do you have to store the pictures on the laptop will you store the files on an external drive and do the editing on the laptop.
Also are you a Windows or Mac user? Also will you us it on the run or at home only, this is important since you will have to check the battery in you new laptop.
So like you can see there are a few points to consider.
