I try to balance work/life as best I can. The commute almost adds 2 hours to the day so I always try for only 8 at the office. I strive for productivity versus long days. I'd rather take a 30 min lunch and leave at 5, etc.
Life is too short to work all the time, but they do compensate me very fairly so I can afford to buy all these toys.
The Apple toys are very important in my life. As I write this on my iPad looking at the Mac mini and new Mac Pro on my desk both of which do the same job. What the heck if you want it and can afford it then buy it. Life is too short to worry about justifying every purchase. And I don't even have an iPhone!
