Microsoft has done lots of new enhancements on their Terminal Server 2008 – yes I would like you guys go for this product from Microsoft.
Yes you can test it in your test environment before moving towards Production and I would say that you results will positive.
There some segregation which has been done in Windows Server 2008 Terminal Server and let’s talk on them one by
Terminal Server Overview
Windows Server® 2008 provides technologies that enable users to access Windows-based programs that are installed on a terminal server, or to access the full Windows desktop. With Terminal Services, users can access a terminal server from within a corporate network or from the Internet.
Terminal Services lets you efficiently deploy and maintain software in an enterprise environment. You can easily deploy programs from a central location. Because you install the programs on the terminal server and not on the client computer, programs are easier to upgrade and to maintain.
When a user accesses a program on a terminal server, the program execution occurs on the server. Only keyboard, mouse, and display information is transmitted over the network. Each user sees only their individual session. The session is managed transparently by the server operating system and is independent of any other client session.

Terminal Server Roles and Features
Terminal Services is a server role that consists of several sub-components, known as “role services.” In Windows Server 2008, Terminal Services consists of the following role services:
Terminal Server: The Terminal Server role service enables a server to host Windows-based programs or the full Windows desktop. Users can connect to a terminal server to run programs, to save files, and to use network resources on that server.
TS Web Access: Terminal Services Web Access (TS Web Access) enables users to access RemoteApp™ programs and a Remote Desktop connection to the terminal server through a Web site. TS Web Access also includes Remote Desktop Web Connection, which enables users to remotely connect to any computer where they have Remote Desktop access.
TS Licensing: Terminal Services Licensing (TS Licensing) manages the Terminal Services client access licenses (TS CALs) that are required for each device or user to connect to a terminal server. You use TS Licensing to install, issue, and monitor the availability of TS CALs on a Terminal Services license server.
TS Gateway: Terminal Services Gateway (TS Gateway) enables authorized remote users to connect to resources on an internal corporate network, from any Internet-connected device that can run the Remote Desktop Connection (RDC) client.
TS Session Broker: Terminal Services Session Broker (TS Session Broker) supports session load balancing between terminal servers in a farm, and reconnection to an existing session in a load-balanced terminal server farm.
