If you want to get started with VPNs and Linux without a lot of hassle, here are some recommendations:
Get A Pre-Configured VPN Router
A pre-configured VPN router can provide all your computers and mobile devices with encrypted internet connections. You won’t have to install a VPN client on each device, and all your devices count as one connection with your VPN provider.
A Desktop With Linux Pre-Installed
