The MacBook Air has been updated with a faster processor, Thunderbolt 3, Touch ID and Retina display. These are welcome upgrades and make a much improved laptop. Although we still prefer the MacBook Pro, the new MacBook Air looks like a good buy.
The Mac Mini can now be purchased with up to 2TB of SSD storage, 64GB RAM and the processor is up to 5x quicker. It also has Thunderbolt 3/USB-C, USB 3.0, HDMI and audio port. This could be an excellent desktop computer, and more flexible than an iMac since you can select your own display. The only thing the Mini lacks is a fast graphics card, which might be an issue if you work with graphic or video intensive apps all day.
