The big question is, of course, whether to upgrade a 6500 and keep it on
life support, or bite the bullet and go for a whole new box. How much time
a -3bxl and careful filtering will buy you does depend heavily on where in
the Internet you are - but I'm willing to bet that a good number of sites
will go for the fork lift upgrade because there are *other* pressing things
coming up that the 6500 won't do either.
Remember - it only takes *one* truly mission-critical "must do" that a 6500
can't, and it's off to a less stressful corner of your network for that long
slide into retirement (on the other hand, I'm sure in 2016, there will *still*
be 6500's installed, just like I'm sure there's still 1996-vintage gear still
out there now...)
I'll concede that Jon is at least partially right - *somebody* is going to
be selling gear... ;)
