As someone else also posted, iPhone can support tethering out of the box as well, provided you have the correct data plan from your carrier. Back when the iPhone 4 was released, I was grandfathered in to the unlimited plan on it. When I called to try to activate tethering (since the contract language at the time was somewhat murky as to if you could officially tether with the unlimited plan) I was told by the customer service rep that I would need to upgrade to the "better" data plan. "Better" obviously meant better for AT&T since I would be losing unlimited in favor of a 2GB cap. The CSR had no concrete answer as to how the new plan actually was better for me except it was $5 cheaper, although he tried to make it sound as if I was losing out on other non-tethering features by having the unlimited plan. He even went so far as to try to tell me that my current data plan was "incompatible with tethering due to technical limitations of the unlimited data plan" and that the 2GB plan "overcomes technical limitations on the 3G network to allow tethering." Right. He obviously could not explain exactly what those "technical limitations of the 3G network" were that disallowed tethering on one billed plan in favor of another billed plan that were both using the same airspace. I took this wording to heart and therefore would have no remorse (very occasionally) using MyWi to briefly tether in a pinch since AT&T's tethering offering for sale is "incompatible with my data plan due to technical limitations." Note that I haven't done this, but the option is there.
As I understand it, the tax break is $1500 this year, and will be going down by $500/yr until it doesn't exist anymore.
(at least that's what the toyota financial guy said last week when I picked up my new prius)
