Most of us have more than one computer we work on our photos with. I have an iMac I use at home for my main editing. It has a beautifully huge display. It’s where my photos live.
I also have a laptop I use when traveling, or when I want to sit on the couch. There are lots of ways to get your photos on both computers. I use Dropbox but there are lots of other great and inexpensive cloud syncing solutions (Google Drive, Microsoft OneDrive, etc). Most of this storage is darn-near free. If you have an Office 365 account they give you 1TB of OneDrive for free. Same thing if you have Amazon Prime, you get unlimited free Amazon Cloud Drive storage. Cloud storage is great. It gives you an online backup you can access anywhere and automatically manages keeping your photos in sync across multiple devices.
