I'm with AmigaHeretic on this one. I prefer base 2. Computers don't think in base 10. Hard disk manufactures only use base 10 because they don't want to sell 0.9 TB disks. It's much easier to sell 1 TB disks with a formatted capacity disclaimer. Some manufacturers, e.g. HP, sell (or resell) disks with formatted capacities that actually match the disk descriptions. Good on them, I say. ;-)
