Hi - forum newbie here with a hardware query. I currently have a Nikon D40 and process raw (.NEF) files on my MBA 11 (mid-2012, i5, 8GB RAM) using Rawtherapee and an external screen. I get the results I want, even if it sometimes takes a little tweaking to get exposure and colours the way I want. I suspect that Lightroom would be a better experience, but I've never been convinced that it's worth £100 a year. For a couple of reasons, I'm thinking of buying a D7000 or D7100. Before I splash the cash, I'd be interested to hear of others' views on: 1) Will the MBA be good enough to handle the bigger files? I'm guessing yes, based on playing around with the samples from dpreview. 2) Is Rawtherapee going to be good enough? If I have to move to lightroom then that's fine, but it may influence my decision to buy the cheaper of the 2 cameras. There may be other workflow options I'm overlooking, of course. Any comments from those who've made similar decisions would be much appreciated. Cheers.
