She's after something sturdy, robust, reliable etc. Not necessarily the cheapest. Other than the internet, storing photos, some work in Microsoft Office that's pretty much it. Not interested in gaming, downloading films etc., so no concerns about graphics cards or huge harddrives.
I'm thinking of the following from http://www.pcspecialist.co.uk:

Total cost is £595.
Going for a 2nd gen Intel chip, SSD drive. Want to keep the cost under £700, will likely get a 19" flat screen to replace the CRT, which believe it or not is still working well. Considering getting the MS Office Home for £82.
