You can itemize work-related purchases not reimbursed by your employer, but only the amount above 2% of your AGI. So, my guess, is no, you won't be able "write if off" from your taxes.
As CPA also stated (I was making the wrong assumption that you had 2% squirrel away)
At a salary $50K per year; the first $1000 of employee business expenses is a throw away.
At a salary $100K (combined with wife); the first $2000 of employee business expenses becomes a throw away.
If you can not get onto the network and IT will not support it; eat the $1500 - personal use will cut into the saving more and more.
An audit by Uncle will state that the employer has provided one for you; ask them for a better one if what was provided can not do the job.
If you have the 2% already accounted for on the Schedule A,the unit is pure work only, then you can lower your taxes by your tax rate * $500
