With the introduction of modern wireless broadband (GSM 3G which is the widest spread standard outside certain technology islands like Japan or I believe Singapore which can support their own standard) the cost of wireless internet has dropped about tenfold. The market has mostly stabilized now. Whereas most of the world was paying insane prices when SMS was the dominant digital exchange by mobile now it costs a lot less.

However in most countries wireless broadband is still insanely expensive for gaming due to metered costs. Amongst countries that meter and cap bandwidth on adsl and cable it's currently averaging about 10% of the cost of mobile broadband (and that gap is shrinking).

We've come a long way from the ninties when a $140USD home isdn line in the US cost $AU110,000 in australia (annually) but we're winding back that way globally. Caps make fiscal sense for providers.

Most capped internet isn't a problem for folk with todays internet habits but will become so in future. It is an added cost and concern when downloading a dvd size game on steam (even though you would get a months worth of playtime out of such a download). It's certainly more of a concern should you wish to download dvd quality video, which is consumed in a few hours, yet may take a significant proportion of ones monthly allotment.

We don't hear a lot of squawking about capped internet yet, but we will in future, and games I'm sure will feature highly in the bandwidth consuming downloads that eat it up.
