Hi,
  I'm trying to get an estimate of the power consumption of the
simputer handheld.

Here are some specs:
CPU: ARM9TDMI
RAM: 32MB
screen size: 320x240

Has ARM got a low power standby mode ?
Would such a device use SRAM ?
How is the price differential these days between SRAM and DRAM ?
I'm guessing that the screen uses little current ?

Thanks for any answers/pointers.

Yes in general.

No. use SDRAM generally

SDRAM 32MB : about 4~5$
SRAM 32MB : too expensive. (over 40$. I think)

If you use back light, it could consume so much current.
consider about it.
