Remote PCs for Browsing Internet

A thin client is a lightweight computer that has been optimized for remoting into a server-based computing environment. As such, it's a generic term and can mean different things. In many Universities, for example, there are thin client terminals which consist of a monitor and keyboard that allow students access campus resources like library searches and student records. Google's Chromebook is a web client, a variant of a thin client, which accesses web resources using the Chrome web browser. With tablet computers now very cheap (see this offer today on Amazon Prime for its 10 inch Fire tablet for £99) you can buy a simple tablet that you can use as a thin client that will allow your employees access your website inexpensively.

From what you have said, a thin client would not be suitable. With thin clients, you need a server-side infrastructure which uses cloud computing software such as application virtualization or a hosted shared desktop (HSD) or desktop virtualization (VDI). As a third party is in charge of your web servers, you would need to set up your own server or get someone else to do it.

What you want is just a web client with a browser like Chrome or Firefox which will do everything you need. Any cheap second hand PC will do everything you need. The bloatware is trivial to take care of - unwanted software can be uninstalled when you set it up. You'll have to update the browser and any OS you install though but that's simple beans.
