Probably won't come as a surprise to those who know me, but we have
used MacBook Pro's with good results. While I've never tried, in
theory a MacBook (not Pro) could also suffice, since internally it's
about the same as the Intel iMac, of which we also have a number
running GNU Radio at full USB speeds.
Various benefits of either a MacBook or MB Pro (or iMac):
* You can run OSX, WIndows, Linux / *BSD, or combinations of these
via Virtual Machine(s). My preference is OSX with a Linux (Ubuntu
for now) VM. Very handy for checking correct functionality of my GR
programming.
* Intel Core-2 Duo w/ good L1/L2/L3 cache. Get 2 GB of DRAM (as 2x 1
GB). Comes with a decent hard drive, but if speed is what you need
then adding a FireWire 800 drive or array will get you plenty more
than 32 MBps of sustained r/w throughput.
* "reasonable" cost given the expected life-span and versatility of
the computer.
* Doubles (easily) as a desktop machine in power, portable for
presentations and demos. This is especially true for the MacBook
(not Pro), at a mere roughly 5 pounds.
If you can wait another month or so, you can probably get the next
generation laptop, which will likely come with the "hybrid" hard
drive which includes a large flash cache to speed things up much
further. My US$0.02. - MLD
