Much as I liked the Arjuna-X WordPress theme that I have been using, it does have its limitations. The main one being that the fixed width display really does require a full size screen and this is not a lot of fun if I want to access the site from my mobile phone. So, after a bit of poking around, I have decided to give Designfolio a try.
I will probably tinker with the theme a little once I have found my way around it but, for now, I am very impressed. Especially when I access the site from my mobile phone.
