Well we have to remember that the cpu in the nokia is running at  
about 200-ish MHz, has a whole 32Kb (or thereabouts) cache, no  
floating point hardware and a 32 bit fairly slow memory bus. If  
you're lucky it will run Squeak at about 5% the performance of a  
typical modern desktop machine. Graphics will tend to be relatively  
worse since the memory bandwidth really bites you.

Nonetheless, actual raw Smalltalk performance is pretty good and the  
UI slowness is down to far too much code running to do the job. If  
you try an older image that has a functional MVC system you might  
well find the apparent UI performance very reasonable. On my very  
old, similarly powered Acorn RPC any morphic menu takes a couple of  
seconds to appear. In MVC, menus are perceptually instant.

Mind you, even on my current dual core 2GHz G5 PowerMac morphic and  
tweak menus sometimes seem to take forever. I take that as a hint  
that some work is needed in the graphics/UI classes.
