Hi Old Boy ... Good advice from Eric ... he's been there and done it.
If your Vista computer is protected by a good anti virus program it should be safe for a few years and if you are looking for a new computer or laptop, do lots of research looking at shop websites etc and eventually decide what you want.
My thoughts ....
Is your existing computer connected by cable to the router ?
Have you already got a large screen which you would want to continue using ?
If so you could purchase a tower desktop which is supplied without a screen but with keyboard and mouse.
It would come with Windows 10 pre-installed. No major upgrades are planned, only updates which download via the internet. Windows 10 comes with Microsoft's new Edge browser but Internet Explorer 11 is there although slightly hidden. Other browsers run with no problems.
A tower computer example can be seen on the link below and I have used it only as an illustration making no recommendation for the store or that particular computer.

If you go for a laptop it will come with Windows 10 as mentioned above, it will connect to your router mainly by wifi but will also have an ethernet cable. One advantage would be that you could get used to Windows 10 etc on it while keeping you existing Vista computer connected. I would go for a laptop with at least a 15.6" screen and although laptops have touchpads I use a battery operated wireless mouse. The usb mouse receiver is so small you can leave it permanently plugged in.

When you first use Windows 10 with it's free Microsoft, account, use a strong password so that anyone using the computer (or laptop) has to enter the password before it can be used. Windows 10 comes with a good built-in antivirus system called Windows Defender which I would be happy to use but I presently use a paid-for antivirus because I remotely cover my young grandaughter's Windows 10 laptop.
One problem with laptops reference your present location is they can easily be stolen.
I have a desktop computer, but mostly use a laptop or iPad sitting in an armchair in front of the TV and not a cable in site. See a pic of it in a recent post here
