T-Mobile bringing HotSpot @Home to your landlines {Engadget Mobile}

Aug 15th 2007 12:58PM I'm having a hard time understanding the use of this...

From what I gather, for an additional 9.99 and expenses associated with setting this up, I'll be able to have unlimited phone usage on my cell at home (when going through the hotspot), along with my normal usage charges while I'm away from home (on the normal cell network).

Is this correct? For someone like me who has NO home line and uses their cell for all calls, this would be a great tool.
