From this type
Most of us born before 1985 are familiar with the round pot. Bragging rights belong to Toshiba who introduced the first commercially successful model in 1955 but in terms of prominence and market share in Malaysia, most likely goes to National (Matsushita). Ironically, Toshiba's first model was the indirect boiling (double boiling) type which gave way to dry chamber direct boiling, the form which we all grew up with and know today. Another player in Taiwan who partnered with Toshiba initially in order to sell more steel, eventually capitalised this method very effectively. Early model only cook and have no keep warm thus the rice has to be moved to an insulated container. In 1960s, Zojirushi introduced the first one with a keep warm function in Japan with other manufacturers soon following suit thereafter. As many forumers have confirmed, the old National appliances are rock solid and you could swear that they still could be working today if not for scarcity of spare parts. As seen here. Another interesting factoid: this method of cooking is called direct heating wherein the outer chamber that encloses the rice pot is dry. Earlier Japanese models were also manufactured as indirect heating aka double boiling but the direct heating models (dry outer chamber) that we are familiar with gained prominence. More on indirect heating method after the next one below this.

Popular in the early 80s, non stick surface within an aluminium core, non detachable cover. Keep warm function by this time becomes mandatory but good for a certain number of hours after which the rice eventually dries out. The pot was constructed to deal with the difficulty of washing the burnt rice off and to evenly distribute heat during cooking. But this is not entirely fool proof as organic substances within the rice also adhere to the surface and forms a difficult to remove layer. Certain manufacturers introduced certain preprogrammed logic in varying the temperature and duration calling models equipped with it as "Fuzzy Logic".

Stainless steel round pot (due to aluminium health scare). The con is not easy to wash but that is overcome with soaking or using the dishwasher. Buffalo sells replacement pots for olden models. Visit their shop or website with the model number of your old round pot rice cooker and they could have a replacement inner pot made of stainless steel.
The other notable appliance company is Tatung who are known for making CRT monitors for those who used to own 80286-80486 PCs. They are the little known innovators from Taiwan and have been known to cook many things with this pot making it known as the "little rice cooker that can". Although this form was the one that Toshiba introduced as the first commercially successful rice cooker back in 1955, Tatung capitalised it to its full potential. Only two functions: cook & keep warm but it packs a hefty multifunctional accessories for steaming and includes a well thought lid holder clasp on the left handle. A unique feature about the Tatung which was innovated by Toshiba besides employing stainless steel is that the method of cooking: water is added to the containing outer chamber which surrounds the inner pot (also has it's own lid) that holds that rice to be cooked. In the US, it's known as indirect boiling but we call this method double boiling. This mode of rice cooking is featured in the Balmuda's Gohan 3Go seen in post #7 below. In Taiwan, electrical supply is 120V. They're sold by Lazada in the Philippines but beware although they're rated at 220V, the phase is 60Hz vs 50Hz in MY/HK/SG/AU/UK. In other words if you buy them, you'll need a transformer to convert the phase to 50Hz. Only appliances rated 110-240V at 50Hz/60Hz are compatible anywhere in the world.
True to their spirit of innovation, they combined the bamboo basket steaming experience that many are familiar with in a rice cooker albeit those accessory being in stainless steel form as shown below.

Microcomputer (micom) controlled. Many models are equipped with timer delay that allows the starting of rice cooking to complete by a number of hours later so that it's ready when you come home from work. Advances in safer material increased confidence of non stick coating. The keep warm function in later iterations eventually allows keeping it overnight without the rice drying out. Early generations used heating element costing 650-850W. Manufacturers like Zojirushi incorporated induction much like how an induction cooker operates thus halving the electricity consumption. Reviews and anecdotes abound about better tasting rice due to the precise temperature control and the type of material used in the cooking pot e.g. platinum. Pressurised induction models combines pressure cooking principle with an induction base element to speed up cooking time and convert the starch to an easy to digest state. Fuzzy Logic improvements with advances in AI and neural network algorithms added into the micom expanded the repertoire of the type of rice it can cook. It is called by a variety of names e.g.Neuro Fuzzy. More on that topic here.

Microcomputer (micom) controlled with unglazed clay pot (better heat retention). China is traditionally the innovator in this field with a proliferation of China made slow cooker made of red or purple clay making head way into the market early too mid 2000s. Most prominent of all is Zisha (purple clay) aka Yixing clay from southern China which is rich in iron oxide. In that US, Vitaclay is one of the many product manufacturer. Locally, Pensonic are among those who produce this. [Update: Elba makes purple clay slow cookers which can stew and make porridge but not purple clay rice cookers.]BMS organics also carries one product.
Surely this device has evolved from uni functional to multi functional of today but that doesn't mean the uni functional type is only used for cooking rice alone.
There are many anecdotes of tricks done with this device esp the good old round small pot. One that's perhaps familiar with some is as a home made sauna for those mothers who just gave birth as used by the traditional confinement masseuse. They will wrap the mothers in sarong as they sit over a stool with the rice cooker boiling water into steam beneath the chair and the mother being wrapped in a bigger cloth to keep the steam in. etc.
Looking forward to hear everyone's sharing experience.
Below are based on Milux micom unglazed ceramic pot multi function rice cooker.
