I don't think so TBH. I'm looking for a laptop at the moment for just that, mobile photography. The fact it doesn't have a DVD drive is a slight inconvenience, but then you can back up on an external HDD instead. The fact, unless you pay £2000 for the SSD, you only have a 4200rpm HDD is the killer for me. 5400rpm is slow when you want to open 30MB images but 4200 is the speed of the dead.
It's a good niche product and the first good looking mac, it's 500g lighter than the XPS M1330 and about half an inch thinner at the back but it is lacking in the hardware area. Stylish people who will only ever use it for word documents and the internet yes, people looking to do intensive work on it, no.
