Yes. Intel has planned a 1GHz XScale processor (which is a StrongARM compatible
processor, so it can be used to power a Palm).
After that there will be 2GHz handhelds.
After that, we will see 3GHz handhelds.
It is expected that handhelds running at 4GHz will come a little bit after.
...
If you are afraid that your investment is outdated in 2 or 3 month, never buy a
computer or a handheld.
