When does your computer become obsolete? Roughly about the time you first unpack it, I reckon...
My old Dell Dimension 4400 was so slick and speedy when I bought it - but that was at least eight years ago - it replaced an earlier Dell that didn't even have USB ports. I maxed out the RAM years ago at 1 Gbyte, and so I can't add more to speed things up. It runs Windows XP.
I also have a Sony Vaio laptop, with lots of bells and whistles - 500 Gbyte hard disk and 4 Gbyte RAM, running Windows 7.
I suppose I'm going to have to replace the desktop some day, but there's a lot of licensed software on it that I don't want to have to replace.
Has M&S lingerie lost the plot?
