Presumably true, but owing the gear means: 1) buying the gear; 2) buying 
backup hardware if you need a "shell" or replacement gear to be handy so 
if something bad happens you can get back running quickly; 3) a data 
center rack to hold the server; 4) bandwidth; 5) monitoring of the 
hardware and having a response team available to fix it. 

The virtual private server market is interesting, but we've found 
various flaws that are make our transition away from owning our own gear 
and data center problematic: 1) they may not offer reverse DNS (PTR 
records) for your IP which is generally needed if your application sends 
out email alerts of any kind; 2) they may have nasty termination clauses 
(allowing them to terminate server at any time for any reason without 
notice and without giving you access to your code and data stored on the 
VPS); and 3) performance will always lag as its virtualized and the 
servers may be "over subscribed."

I like the Amazon EC2 solution, though the pricing is overly complex and 
they suffer the "no DNS PTR" ability.  But since you can buy just what 
you need, you can run warm standby servers or the like and moving your 
data from one to the other over the private network costs nothing 
extra.  I found their choice of OS confusing (we wanted CentOS, but they 
have no Amazon-certified versions), too.

Does anybody have any recommendations for a good VPS provider?

Thanks,
David
