Yes, well, extra fancy effects do come at the cost of battery power. That's actually why I think it'll mostly be limited to games, at least on platforms such as Tizen. Samsung (I think it was them...or their engineers at any rate) pushed for EFL because it was fast, and efficient. They basically got a smoother interface using less cpu time, and they won't want to ruin that. This is also the reason I use E17 over anything else - it's smooth, no clutter, and uses minimal resources. Rasterman is a bit of a perfectionist, but it pays off.
Also, a lot of interfaces are using hardware acceleration these days - older, pure CPU stuff can sometimes use more power as a result. I do understand where you're coming from though.
