The new 2016/2017 MacBook Pro is a fine looking piece of machinery. It packs a legitimately high-end display into a svelte package and it also offer excellent battery life. For a graphic designer or individual that deals with an exclusively Apple ecosystem it is a splendid update to a historically solid line of machnes. However, for an attorney and IT professional dealing with legacy applications and a variety of real world situations, there are some major drawbacks to Apple’s mobile workstation.
Currently, as of September 20th 2016, the best GPU for mining Ethereum is the AMD RX 480. The criteria are cost, hashrate (in MH/s) and power usage. My current top pick is the Sapphire Radeon NITRO+ RX 480 8GB model with 1342 Mhz core clock speed, for approx 27-29MH/s. At current rates this $279 card should mine about $750 USD of Ethereum a year. 4GB or 8GB? 4GB models of the RX 480 offer a lower initial cost, but resale value
[Scroll to the bottom for a quick video of the upgrade process!] The Lenovo X230 (and its predecessor the X220) are absurdly easy to upgrade.

For the upgrade, I chose Crucial’s excellent 16GB DDR3 RAM kit

An incremental upgrade for sure, but one that has left me satisfied and feeling like I am good for another year or two at the least. The price was right and the upgrade-ability of these models is superb.
The Dell Latitude E7450 is a capable 14″ Windows laptop. Heavier than an ultrabook, less capable than heavier workstations… it strikes a fairly good balance between portability and performance. My favorite feature is the E-Dock compatibility, allowing for easy multi-monitor use when docked at a desk. The laptop’s keyboard backlight is also very handy when working at night 🙂 Least favorite aspects are limited battery life and only decent keyboard/trackpad/trackpoint. I find that I prefer my classic X220 for typing
The Lenovo IdeaPad 100s is a reasonably priced lightweight Windows laptop. Unfortunately, limited storage and poor display viewing angles prevent it from being a machine I would use on a daily basis.
