Keep a drawer of old crap around.
Stuff gets broken, but if people get rewarded for breaking their older stuff with a new shiny replacement there is going to be a lot of opps, it broke (especially in the sales and marketing departments).
Sales #1 gets a new Blackberry (the old one was over 4 years old).
Sales #2 my Blackberry broke, I need a new one.
Me. Well it's only a year old, so we will get it repaired or replaced with a referb. While you wait you can use the loaner... did you know that this was the first colour Blackberry? It used to be owned by the CEO! (the look of horror on sales #2's face is priceless).
Sales #2 but sales #1 got a new one! Why don't I get a new one!
Me. His phone was 4 years old, so he automatically gets a new one. Your phone will qualify in 2 more years.
My opps it broke loaner laptop is a Dell D800 with the letters warn off the keys (they were tanks, I still have three of them, and they are about the same weight as a tank too).
