X230 ThinkPad vs 2016 MacBook Pro

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.

Best Ethereum mining GPU [Sep 20th, 2016]

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

My X220 ThinkPad has finally started getting long in the tooth. Therefore, a replacement is in order. After perusing all the latest and greatest laptops of 2016 (XPS 13, XPS 15, ASUS, HP, etc.) I settled on the Lenovo X230 ThinkPad. 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. I

Dell Latitude E7450 1080p IPS

OLYMPUS DIGITAL CAMERA

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 and
