Power Servers last forever
As a POWER system customer (i5 o/s in my case), I've made this comment before on articles like this: You only have to buy these things once every 5-8 years. In last 10 years or so, once they reached status where you don't grow out of the CPU and storage, I've moved to a six year replacement cycle. And if business is bad, I have no qualms about stretching another couple of years.
You can't kill these things with a stick, still by far the most stable, most productive business servers in the world. Mainframe capacity/performance that is so productive that many shops have one IT person who doubles as developer/admin, like I do here. And we aren't talking green screen apps anymore, I'm currently connecting Sencha Ext JS apps to the server.
The last point is that, unlike a loaf of bread, everytime I buy one of these it gets cheaper with 10 times the performance/storage of previous server. And I mean WAY cheaper. In 1999, (before they had integrated POWER line), our AS400 was $90K+. In 2004, it was $50K. In 2009, it was $20K. When I buy POWER8 next year, may be as cheap as $10K. How you going to see any revenue growth when that is going on?
