I have a mid-2010 2.66 GHz Arrandale i7 Macbook Pro. I also have an iPad Air 2. I don't use my computer much these days, I have it docked on my desk with a 24" LED Cinema Display circa 2008. That said I still love the slab sided 15" form factor (would obviously prefer a retina version). Screen real estate is nice, but not crucial since I have the ACD. I do still need a computer though, easier to pay bills, update my resume, etc. A computer still has a place, and it's nice to sit at a desk sometimes since I have a home office. I use my iPad all the time, but find it can often be uncomfortable to use when laying around, holding it up laying in bed, etc. I often find myself thinking it would be easier to just have a small laptop instead. I'm still considering keeping a 9.7" iPad and at some point going all out on another 15" retina MBP (skylake or better, and hopefully a vaporware retina external display if Apple ever makes one), but I was also thinking about consolidating my devices, spending substantially less, and ditching both the 15" MBP and the iPad Air and getting a base Macbook (will never need more than 256 GB storage, I have a 128 GB SSD in my 15" now and it's got lots of empty space still). That said, I will not go down in performance, but a tiny computer 6 years newer than my old turd might have new enough technology to outperform even my top of the line 15". So, how does the M3 compare to my old 2.66 Arrandale i7, performance-wise? Assuming it's better, then the only thing I am stuck on is deciding what to do with my ACD, either get rid of it and live with just the 12" Macbook, or do the expensive and not clean solution to get it to work with the Macbook (saw a solution online last night that costs about $120 in various adapters).
