Harking back to induction devilry for a moment, Mrs. Wow and I treated ourselves to one of these:
Clickyon the grounds that, apart from it being a pretty crap, cheap model, there's not a lot wrong with our gas stove. We bought it deliberately as a very basic model when our old one packed up. We had fallen foul of a very prolonged power cut one year when there was a LOT of snow, and no leccy=no gas central heating. With the other gas stove, it meant no oven either, so we got one that didn't depend on leccy.
However, back to the consumerist trash referred to above. It's generally pretty good, with some pre-set programs. Its hotter modes get the pan very hot very quickly. It has a program for milk, so it doesn't allow it to boil over, and it is excellent for porridge. However, it has a "Stew" mode, which it touts as a slow-cooker substitute. Except that it has a timer that turns it off after 2 hours, and so far as I can tell there is no way of extending this time. That makes it utterly useless as a slow cooker.
Edit: I finished the stew on the lowest of the 9 manual settings. The stew was boiling very gently. However, after it had finished, some of the stew had been "caught" by the heat and there was some marginal carbonisation at the bottom of the pan. It surely must be possible to keep a large pan on the boil without the base burning?
