e310 questions

i finally got a new arm based ppc. my question is can i still use the original 3.0 evc to make ppc 2002 programs, or do i need to upgraded the dev kit?
Are there any issues that may complicate my transition from my casio e-125 to this tosh. e310?
I asked about back buffers and such before, but does the e310 write to the video directly or does it stay in the back buffer prior to calling gxend or what ever the function is.
thanks for any info you guys may have.
ps. what everyones thought on this ppc compared to and ipaq.
