[quote]Ron Schaeffer, head of product strategy and planning with the Birmingham, UK-based mobile phone start-up told ComputerWire that he believes the GPRS-connected Z100 will cost in the region of 299 pounds ($460) with a contract, and 600 to 700 pounds ($930 to $1,085) SIM-free.[/quote]

Rafe's Comment:
This seems to be rather expensive to me. It will be undercut by the 7650 in some cases (the Link are advertising the 7650 for £250). This puts it more into the price bracket of the superior P800. It seems that with this news and its late arrival the Z100 is going to face very stiff competition. Not that's going to upset any Symbian supporter...
