One of the questions I get asked frequently from my start up clients is "which computer (printer, scanner, fax, etc.) should I buy?" It's a reasonable question, nobody likes wasting money and law firm start up capital in particular should be jealously guarded.
Because technology is constantly moving, I know the answer I gave last year or last month is no longer reliably still the right one. So, I research the options pretty regularly. Over several years of researching, I've come to rely heavily on two resources: the Wirecutter and Amazon.
The Wirecutter is a curated list of best in class technololgies, from laptops to mobile phones to GPS watches. It makes everything scannable on the home page so you can find the guidance you're looking for quickly. In product categories where I am educated enough to have my own opinion, I almost always agree with The Wirecutter's recommendations. For products I have bought on their recommendation, I have yet to be disappointed or surprised.
Amazon is my second resource. I use it as a crowd-source double check (not to be confused with a discount double check) my selections. I log on to Amazon, choose Electronics & Computers, choose the subcategory (say, Laptops & Tablets) and then sort by Best Sellers. The best selling and highest rated products are near the top of the list making the shopping easy. In general, the wisdom of crowds has been a pretty reliable guide on these decisions.
Scanners - The Exception to the Rule
The one exception to this process is choosing a desktop scanner. Neither The Wirecutter nor Amazon yield the product I most frequently recommend to lawyers in search of a desktop scanner: the Fujitsu ScanSnap family. The ScanSnap is a family of single-function desktop scanners. They are exceptionally popular among lawyers and the folks who advise them for a bunch of reasons. Ernie Svenson writing for Paperless Chase outlines it thoroughly here, and I agree with his analysis.
