Via Cybernet I discovered that Logitech have updated their SetPoint software - I use an LX7 Cordless Mouse on the laptop (in addition to the touchpad).
I haven't had a chance to download the software, but what caught my attention was the size of the download: 55 megabytes.
What the? It's software for a mouse. Just exactly how many lines of code does a mouse need? Aye ca rumba.
But hey, the Ed Botts of the world will tell you all is okay because memory and storage is cheap, which means the efficient coding is for the birds so long as the software gives you the impression that it works.
