Another query for a laptop. A friend's friend need to buy a laptop. His primary requirement is good performance and ample storage space. He said that the laptop would be used for downloads over the internet (!). From what he told me, I think he runs a mobile store type operation and has to deal with software/firmware upgrades on a daily basis.In any case, I guess he should be able to install the OS himself so both OS and non-OS model suggestions are welcome.
