What I use
Because I am occasionally asked, here is a list of the tech items I use on a regular basis.
Phone and Wireless Carrier
I have left the Apple ecosystem, and now use a 64 GB Google Pixel 3 XL with a Tech21 Evo case. I am completely delighted and recommend both phone and case highly. I have transitioned to Google's Project Fi as my wireless carrier, and I recommend it highly as well if, like me, you are frequently connected to Wi-Fi.
I use a 14-inch Sony Vaio laptop running Windows 8.1 that I purchased from the Microsoft Store, so it came with no crapware. If you're going to buy a Windows computer, I highly recommend purchasing from Microsoft for that reason.
My current primary tablet is an Amazon Fire HD 10.1. I've used a succession of Amazon tablets, from the original Kindle Fire to the $49 Fire 7 to this one, and have found them to be excellent affordable tablets for my use case, which is primarily consumption of Netflix, Hulu, and Amazon Video. I've installed Google Play on the 10.1, and now i have an affordable Android tablet with access to all Google services. I'm calling that a win.
I use an Amazon Kindle Paperwhite, which is the best e-reader I've ever used, and is also the best currently available. You can buy more expensive models, but don't waste your money. This is the one you want.
I have transitioned away from Dropbox for everything but my e-book library, and now use Google Drive for everything else.
After years of trying everything under the sun, from Blogger to Wordpress to Posterous to Tumblr to Posthaven, I've landed on the 10Centuries platform developed by Jason Irwin in Japan. I recommend it highly.
