The IRS is already thinking about including those perks as part of your taxable salary anyway...
In Aus (and UK, I believe) you can "salary sacrifice" something like a car, phone, or computer. Essentially the employer buys it for you and just deducts payments from your paycheck towards it. It isn't income to you, but there is a fringe benefits tax. Some items, like computers and phones, are exempt from this tax though.
As a result very few have any real perks, except free cell phone. At list it makes it easier to compare job offers :)
