^ Airbook Pro? That would make the decision so much easier if they actually existed!
If you're really into editing and photoshop I would suggest the Pro as well. They're not that heavy, I've been carrying about my old 13" MacBook for a few years and while it's a bit of a weight it's not unbearable if you have a shoulder bag with decent straps.
I don't know what your budget is, but I would go for the upper level 13" one. I think you'd benefit from the extra 4GB RAM it has (I have 4GB in my current Macbook, I use it for similar things to you and it's not enough) it has the big hard drive for storing all your stuff.
The Air wouldn't be a bad choice (if you specifically wanted something lightweight) and it has the SSD which will make it overall quicker, but I'd go for the Pro in your situation because of the RAM and HD size (but again this could be solved by buying an external hard drive in you really want an Air).
You won't regret buying a Mac, I was unsure at first when I bought mine (4 1/2 years ago) since my family are all windows windows windows, but best decision I made. I've just bought my second Mac (Retina MBP) and I don't think I could go back to windows now!
