It ain’t cheap (retail price: $1,499), but Lexar has a new four gigabyte CompactFlash memory card out. Let’s pause and think about this for a moment. Four gigabytes is enough to store as many as 45,000 JPEGs, which is probably more photographs than the average person will take in their entire lifetime. Eventually, as camera resolutions improve and file-sizes get bigger, filling up a memory card this large will get easier, but in the meantime it’s unlikely that anyone apart from professional photographers (and very serious hobbyists) will shell out the cash for one of these. Which is just as well, since these new cards are only compatible with a relatively small number of high-end cameras like the Canon EOS-10D and Kodak’s DCS Pro 14n.
