Which option is better given they have similar price and shipping date? I will mainly use this machine for travel and some coding work (xcode/web). Also I need to run windows version of excel a lot so need VM for that. In terms of storage, I have 16TB home server at home as well as several TB paid cloud service. In theory I don't need huge space on laptop. But I'm still concerned about 256GB mostly due to my experience with iPhone. My last iphone is 32GB and I got low space warning after half year usage (taking a lot of photos/videos and some large apps). I hate to be forced to clean up photo/app since i will be panic about choosing what photo/app to delete. In the end I paid huge premium to get 128GB verion. I guess laptop is different in usage pattern but the idea that sync with my iphone already take more than 1/4 of the space worries me. I haven't had a laptop for 5 years and never had any macbook so I really need some inputs here. Does mac os system size increases as time like windows? Is there easy way to keep only favorite photos on laptop and keep everything else on cloud? Is 256GB generally enough (with cloud server)?
