This gets more amazing all the time! It's practically ALREADY in the Palm.
I have to ask - I seem to have missed out on all this detail and I'm wondering where
it's presented.
I have the OS4 SDK and all the documentation for it available on the Palm Dev Seeding
area. But I seem to be mising a lot.
Where is the best place to find low level detailed information about OS4?
I don't know why, but I'm finding it a bit strssful trying to keep up with the
dizzying pace the Palm is evolving - and this is
NOTHING like what happens with OS 5. After the transition to OS 5, will we get a bit
of a breather?
I can see it now...
"Well, actually Jeff, if all goes well, after OS 5 we will then switch to the EPOC
API...." ;)
