i think the issue here is that a search is one service payed by another (adwords) and so on.
for the cost of a search you have to devide all employees into their group and take out only the cost for searches. but than comes adwords and pay for it...
tough the adwords code probably runs on the same servers that deliver searches (unified system)... i guess its really hard to cslculate but i would guess a search is only a fraction of a cent even before balancing it out win profits.
for xmas 1989 i got a C64. my uncle, big show off, got my cousins (two girls) an amiga. why? cause it cost a bit more. turns out amiga sucked and my C64 was pretty much awesome until i got a 286 a bit later. i even remember begging for 4MB more RAM so i can play rise of the triad ... anyway, thinking back it kinda feels like the C64 was a more open platform and everyone else was pretty much fucked.
