Here is what I use on a day to day basis (updated : July 20, 2015):
I use a Dell Latitude 7440 Ultrabook. Am running Windows 8.1 and this lightweight has enough battery life to last me a full day.
Dell All In One (AIO) running Windows 8.1 as my main system. Also use several Western Digital “MyBook” type network drives to backup my data as well as use DropBox to backup non-confidential data to the cloud.
Apple iPad mini with 16 Gig RAM.
Apple iPhone 6. Have developed a few apps for the Android platform and am looking to try my hand at developing iApps.
USB Memory Device
To ensure that my portable data is encrypted I use Apricorn SecureKeys as well as their Secure Drive.
Apple IIe (vintage in excellent working condition)
I have a fully functional and mint condition Apple IIe computer along with dual disk drives, Apple mono monitor (green) along with a complete version of AppleWorks software, box and manuals. I used to service these systems (at the chip level) many years ago.
Data General One (vintage in excellent working condition)
Was fortunate to acquire a Data General One laptop with power supply and carrying case. Surprising the battery still functions. More to come on this vintage unit.
Web Hosting and Cloud Computing Services
Have been using many different web hosting services but am now using GetFlyWheel.com, Amazon Web Services (AWS), Google Cloud Computing , Digital Ocean and Frantech’s BuyVM services.
