I realized at some point recently that when I teach and when I present at conferences, I am using my personal laptop, putting it at risk when my university should be providing me the proper equipment to do those things. Fortunately, I have a bit of money left over from my professorship, and so I looked into what my portability options are:
One consideration would be the 11-inch MacBook Air, now discontinued (and never given the love it deserved):
Amazon has one for $700: Apple MacBook Air MD711LL/B 11.6-Inch Laptop (1.4GHz Intel Core i5 Dual-Core up to 2.7GHz, 4GB RAM, 128GB SSD, Wi-Fi, Bluetooth 4.0) (Certified Refurbished).
Apple has one for $849. MacBook Air 11.6/1.6GHZ/4GB/128GB Flash. March 2015.
Or one for $929: Refurbished 11.6-inch MacBook Air 1.6GHz Dual-core Intel Core i5. Originally released March 2015. 11.6-inch. 4GB of 1600MHz LPDDR3 onboard memory. 256GB PCIe-based flash storage. 720p FaceTime HD Camera. Intel HD Graphics 6000.
With that price, I thought I should look into something more readily affordable: the 9.7-inch iPad Pro Wi-Fi 32GB – Space Gray released in March 2016 lists for $579.
That’s not bad, but I a colleague of mine recently ordered one and I took one look at the size of the keyboard and thought: no. So that leaves the more expensive option, especially since my university won’t buy refurbished gear of the MacBook: 12.0/1.1GHz Dual-Core Intel Core m3/8GB/256GB Flash. April 2016. $1,249. (There was a refurbished version on the website for not a lot less, $1189, but it did have a 512GB SSD. Win some, lose some.)
