@Mike Martin What type of phone do you have (Apple or Android)? You might consider getting a laptop to match so you can share apps a little easier.
Specs: 8GB of memory, 256 GB of storage, i5 (8th gen processor or later) and a 14"+ screen size is a good place to start if you are going to download property software and store a lot of property photos on your system.
Chromebooks don't have an operating system (meaning you don't have Microsoft Windows, so no excel, word, PowerPoint, etc). I personally use excel a lot for spreadsheets. Basically, Chromebooks are popular b/c they are inexpensive but it's not much different than a tablet that gives you basic internet.
I personally think there is no better computer that exists than the 'Lenovo ThinkPad' brand of computers. They are the only computers that are military spec'd which in short means you can spill your cup of coffee on the keyboard then drop it on the floor then just pick it up and finish sending the e-mail you were just working on, literally.
The Lenovo website is showing a ThinkPad T490 on sale for $849 right now with all of these specs, I'd recommend this one. It's basically what I have.
