With the last money I had left, I bought two cameras for UI comparison testing. A used Sony Cyber-shot DSC-T50 with a touchscreen UI and a new Canon Powershot A490 with a standard UI. Sadly I could not afford a Sony with a newer touchscreen interface, so this one will have to do the job. Here is a picture of all the cameras:
Because I have no money and no time to spare, I will also have to leave out all the summer festival. I already missed Nova Rock and will miss Metal Camp and Sziget. And all this isn't actually boosting my motivation...
By the way, I am planing to do 50 UI comparison tests and for this I will need 50 people. So please contact me, if you are interested. One test should probably take around 20 minutes.
