Cell phone, computer plus programs (BidBest, etc...), I bought a back-up hard drive last year and itemized that also, ISP I also claim, uniform dry cleaning (yes, even the pittance at SFS), uniforms over the company limit, cab fares I had to pay when I didn't have a dev bank to cover them, mileage to/from the arpt for work, and last year I bought a backup pair of Rx glasses to put in my bag, claimed those too. All of this I claimed as a professional business expense.
I couldn't figure out either how to claim an airporter car and I no longer have a crashpad.
The per diem deduction has a potential to be huge. For example, the US Gov't ALLOWABLE daily per diem rate (from the IRS.gov site) in KIX is $191.00 per day as of 1Dec07. FedEx only pays $64.80 max per day ($2.70 x 24 hrs). In '07, pilots are allowed to claim 75% of the difference (in '08 it goes to 80%). See your tax guy/gal, your mileage may vary, I stayed at a Holiday Inn Express last night, yada, yada, yada.......
