Owning vs Renting (or in this case subscribing)

Ben posted about software a few weeks back and I recently have been researching options on purchasing said software (Adobe, etc.).  I came to learn about 

Adobe's Creative Cloud.  Instead of a one-time-fee purchasing type, one can subscribe. 

I believe there to be many perks, for instance receiving the most up-to-date versions and upgrades, Cloud storage, and even prototype program releases.  There are also cons, which are mostly based on the user.  I one were only to use 1 or 2 of the programs, and is not interested in receiving and exploring cutting-edge technology, then it may not be necessary.  

Adobe says  that it aims "to provide you with maximum flexibility, lower cost of entry, and most importantly the ability for Adobe to deliver cutting-edge innovation on an ongoing basis, to keep you ahead of the changing technology and device landscape."
