RE: I suspect what happened
When I used to build pc's the goalposts changed constantly. A better component would be offered at more of less the same price so I would get that instead, sometimes the usual component would be not available or increase in price. Hard drive capacities would be a good example of this, all other things being equal. There are however examples where bigger/better can cause problems though - with Hard Drives there can be BIOS gotchas, if not careful.
