usually general memory consumption. I can't say for this new GUI, but last time I tried matchbox was consuming much more memory than e17, even the last having animations and bling bling (more pixmaps to load). Again, I can't say anything about new gui, clutter is not memory heavy per se. So I agree with you, we need some data to backup those claims. >> With the increase in hardware capabilities in current >> devices this can probably be accommodated but I personally would have >> liked to have seen some Moblin-2-lite (perhaps based on EFL) which >> runs on very low memory/processor systems > > Something like EFL will generally starve your CPU much more than the > likes of Clutter or anything else using the GPU (over the CPU) for heavy > graphics operations.

You really don't want your window manager/system to be the most brilliant start in your device, but rather the application that do something useful. Of course your wm should comply with the rest of the system and provide something on par, but it's not the main component there, it should be perceived as invisible, did anyone say "oh, how good is iPhone's window manager"? No, it's invisible, people say "Oh, that note taking application does zoom when you select the cursor!". As for rotations, yes, they're not in EFL, but Canola managed to be the most eyecatching application for Linux ever and does not require it. IOW, it's not all about pure technology, it's about getting excellent designers to work together and come with good solution to user needs, not about doing crazy window effects every time user moves an window. And WRT that Edje plays a big role in enabling designers and developers to interact, see INdT porting Edje to QT (QEdje) in order to deliver the same high quality products on top of Qt (an excellent, featureful and very optimized platform btw). Last but not least, Evas does have GPU acceleration, just use either XRender, OpenGL, Quartz, ... we just don't have OpenGL-ES for lack of demand AFAIC (if you have demand, just pay us and we'll proudly do it for you ;-)).
