hold on cowboys :-) the next SDK's emulator will not simulate an OpenGL ES chip, which means that, while the system image may have support for hardware-accelerated rendering (and not only surface composition, as in M5), the system will default to the same software-only code running in emulated ARM machine code, with our slower-than-real-life framebuffer emulation.
the difference should only be noticeable on real devices, which are not available yet. there are plans to add EGL emulation, but it's not going to happen very soon since our system still works well without it. apart from that, everything that hackbod said is very, very, true... the computations necessary to perform high-quality anti-aliased path-based rendering are a *very* poor match to the capabilities of graphics hardware in the embedded world (and even on the desktop world, unless you have a recent GPU). I also do not know of *any* graphics system based on scalable vectors that doesn't use cached pixmaps to significantly speed up animations (OS X, KDE 4, etc.. included).
