If Sony were to buy Nokia, I'd put Nokia on my blacklist. There's nothing worse than having a device which is laden with DRM/SCMS technologies in which Sony has been pushing since the 90's.

Whoever thinks Sony is a nice company, they ought to be wronged in several ways as Sony gives you far less freedom than what Microsoft and Apple would even provide. In addition to what lma said, they have traumatised their own MD users/owners and their sites along with their databases has been sabotaged many times. Also Sony is suing its own hacker community which they initially started this whole kaboodle about OtherOS support. As PS3 hacker tries to restore that functionality, guess what? Sony sues him.

Nokia is slightly more hacker friendly than what Sony is, period.
