I just ordered a 702... CF is so cheap now you can own more memory than the HD for approx the same as the HD Cost, keep things solid state and eliminate the HD and any possible heat related issues...
To be fair, outside of a Cochella Festival shut down with a very early Firmware 1.34 or something like that - I have never had any thermal issues and have run in 100+ Degree heat at ACL twice.
I really like the CF Media for simplicity and reliability, my HD-P2 was nice but I just did not like the machine, the R-1 / 9's seem to be pretty good choices... I just like CF and with prices falling so rapidly and 32 Gig cards coming in the (hopefully) near future it has become my choice....
My Two Cents..
