In a situation like a business trip, where the machine absolutely has to 
boot in order to do the sales presentation or demo, then a secondary 
traditional HD is a smart move.  Mirror the system image just prior to 
the trip onto the external drive.  If the internal dies, swap drives and 
carry on.  It's a $50-$100 investment vs not having a bootable drive at 
all.  If it's that important to you that a drive failure would kill the 
trip, then you should be doing even now with traditional drives.

All the user data should be backed up either to an external device or a 
server somewhere (including the data files required to do the 
presentation or configure one-of-a-kind software).  Which means that 
even if the backup drive is a few days out of date, you should be able 
to drop it in and synchronize the user data back up with the external 
source within a few minutes.

I'd also still stick with the bigger names in SSDs right now.  Intel for 
sure, then maybe consider the lesser players.  The oldest SSD we have in 
use was bought back in '09 and that unit has shown zero issues.
