Other than this? i.e. the internet.
While the LHC may not be about to give you a new version of the microwave a lot of the 'spin-off' tech is VERY useful (HTML, radiation imaging for medicine, modeling systems used in finance etc click here for more). More direct uses are common as well this is a report from CERN on a new experiment that's just starting up to look at how cosmic rays may affect cloud formation and climate change. There are also experiments being designed that will create x-ray lasers (XFEL, LCLS and one in japan who's name I forget)use linear electron accelerators, to create x-ray lasers that will allow us to probe matter at even deeper levels: being able to image the absorption of chemicals into a cell, for example.
Anyway that's it - just a micro-rant on "what have the particle physicists ever done for us?"
