The other day I was going through one of my semi-regular musings at how incredibly fast the world's computing prowess has developed in our lifetimes. On this occasion I was with some work colleagues and we'd been discussing the amount of computing power in mobile phones; for example, the one I've just set up (six months after taking delivery of it!) has 8GB of storage.
All of us in the conversation were old enough to have worked with both of the most common formats of floppy disk. So, we set about trying to work out how many floppies we'd need to equal the storage capacity offered by a finger nail size storage device on the phone. It seems that it would have been roughly 11,000 of the 3½ floppies (the hard cased one) and about 22,000 of the older 5¼ version.
In my inbox this morning an exhortation from Amazon to buy a 1TB external hard disk - that's 1,000 gigabytes - for under £80. Unreal.
