For IT professionals - how much of your tech purchases do you itemize?

Curious what people are doing around here. I am pretty much of the mind most of my tech purchases, since I am in a technology related field, I can itemize.

Basically the only things I haven't itemized is my tv, receiver and speakers. I itemized my HTPC, as I use it for some work purposes. My iPad, I itemized, same with my phone, laptops, even my kindle.

Just curious as to what others do. maybe this is a money board thing.
