My eldest daughter, Sky (19-and-two-thirds), has just purchased a new mobile phone. It has the facility to accept a 'transflash' memory card. The one we ordered just arrived; a 1 gigabyte unit measuring 1 x 10 x 15mm (fingernail size). It cost less than three chart CDs.

The first external hard drive I possessed was bought for a Macintosh Plus in 1986. It was about 70 x 220 x 220mm, and weighed at least a kilogram. It was the largest capacity available at the time, 20 megabytes - a FIVE-HUNDREDTH of the capacity of the aforementioned memory card. And it cost me over 600 (plus VAT).

I'm still in a mild state of shock. Read more on my blog.
