The answer here is: It depends.
You are not going to find a new laptop with a floppy drive, but external floppy drives might be available. I would replace the floppy drive in the machine with a USB adapter. Something like this.

The other question is what operating system is compatible with the software that you are using? Will it run on Win10? All new computers are going to have Win10 installed. It's not even possible to install WinXP on some of the newer computers, Win 7 will install on most, but not all.
