My 8 favorite tech products from 2015

What do a smartphone, two tablets, a SIM card and some smarthome devices have in common? They're all among my favorite tech items from 2015.

Among the many tech products I've purchased and reviewed this last year, these eight have made their way to the top for various reasons. It's a wide range too: one smartphone, two tablets, a SIM card -- really! -- and some smarthome products.

While they may not be the best for everyone, they've kept me happy and productive in 2015.
