Sony needs to try and expand their business in other avenues to generate more profits. They haven't really done well on that post the PS3 years, and they are about to shut down their Vue TV streaming service.
I know it would be risky to jump back into laptops again, but they could try expanding in other technology sectors. Also they need to reboot their phone division, try to actually get along with carriers, and this time without being exclusive. Tier their phones better to the entry level isn't a dumpster fire phone after the consumer buys it.
I liked their product line-up when they still had retail stores but that got shattered during the PS3 years Technology is more popular than ever, they should be able to jump back in now that they have stabilized the company.
