You have to pay for your bandwidth (and even if it's a=20 flat-rate, the maximum amount of data you can get through is=20 bandwidth*(seconds per month) for one month fee). Hardware is replicated as= =20 well as software, the cost for hardware replication is higher than for=20 software replication, because more things are to do. The basical principle= =20 of producing a CD-ROM and a chip is exactly the same: lithography.=20 You "print" it. A decade ago, ES2 had made chips by direct e-beam=20 lithography, so the offset of the mask costs were eliminated.
