Sony encompasses a lot of things, working as a salesman at JB HiFi for the past 5 years has added plenty to how I see sony.
As far as gaming goes, I like sony, I like the PS3, I liked the PS1 and 2, I liked the PSP (after I was able to get CFW running and all that) and I even own a Vita now but in gaming the only ones I dislike are microsoft.. I loved my segas and I doubly love/d my nintendos (The gamecube is still my favourite console).
Now for other things;
Sony's TVs are overpriced and quite frankly rubbish in comparison to a similarly priced Samsung or LG - The colour palette isn't everything but for some reason sony seem to think it is.. and they sacrifice motion rates and smart TV functions to get their brilliant colour palette which is only marginally better than cheaper samsungs that also have a smoother picture (better motion rate), built in wifi and a thousand and 1 other smart tv functions.
Sony laptops are also overpriced, a backlit keyboard (on the vaios) should not increase the price over an identically specced laptop from dell or asus by $200+.
Sony has recently picked up in the phone market (which is my area of expertise, telco at JB hifi and telstra before that), the xperia z is a fantastic smart phone and I actually own one myself (along with a s3 4g and note 2), the waterproofing on such a sleek, high end device is nothing short of amazing, problem is, in their rush to get to the market first they have sacrificed performance vs. the next 3 next gen devices - the newer chipsets in the Samsung S4, LG optimus G pro and HTC pro just destroy sony's older snapdragon so it will suffer.
Overall, I like sony, I think (in recent times) they have been making better and better decisions and they have been producing great products (albeit some overpriced, but they are still good products).
