So I'm finally replacing my ageing Macbook from 2008, and as I have and iPad and iPhone, plus being on a stricter budget now, I've decided on the Mac Mini i5. My question is has anyone ran it withe the 4GB included? How was is? How strongly would people recommend upgrading to 8GB? I will mainly use it for watching movies, browsing the internet, using iWorks and home photos etc. I'd prefer not to fork out the extra but I don't want to compromise on the experience. Thanks for your opinions!
