I'm thinking about getting a new MBA and I have to decide about configuration. Basically, I could go with 8GB RAM and 128 GB SSD, or 4GB RAM and 256 GB SSD. I would use it for mostly Internet/Email/Video with occasional use as a travel version of my business CPU, which means Dreamweaver, Photoshop and InDesign. I can certainly make 128GB of storage work, but 256GB would be nice but I really want to avoid the spinning beach ball. Thoughts?
