Hi:
This is a very subjective question...to anyone that's using Squeak on your handheld of choice, I ask: How responsive does Morphic feel?
Although I'm still struggling with an unoptimized VM on my iPaq, I find Morphic to be a bit...sluggish. It's not horrible by any means... but it is a bit slower than I was hoping. Dragging morphs particularly slow (due to the drop shadow perhaps?). Stuff like character recognition seems a bit slow as well, but it's certainly usable (just not as fast as my Palm IIIc). I haven't had any time yet to look at potential bottlenecks.
I'm just curious, is all...I'm still looking in to getting the build chain fixed on handhelds.org (I've already brought it up on their mailing list).
