Difference between Windows 2008 and Windows 2008 R2 in Terminal Service

Is there a difference between Windows 2008 and Windows 2008 R2 with respect to remote desktop service (connection speed, memory management ... etc)?
R2 is quite more expensive to buy on Ebay than regular 2008, but I wonder if it worth installing R2 when the users use remote desktop connection to connect to Terminal Servers?

Yes, there were many enhancements to 2008 Terminal Services.  The most meaningless was that it was renamed Remote Desktop Services.

Look at the index on the left - each section details new features - see link below.

@Lee,
 
I can't really see where I would benefit by going with R2 when the users run MS ACCESS database program, run Word/EXCEL/OUTLOOK, Web browsers, local printing.
I saw USB re-directing ... sounds handy, but not sure where this would come into play in everyday work.

I would consider it if R2 provides faster connectivity (from workstation RDP to TS), attach local printers to the session better..

You didn't mention ANY of that in your initial question.

You should be aware though, you MUST use a Volume License Edition to install office on an RDS/TS system.  Further, I would consider it penny wise/pound foolish saving a few dollars going with 2008 when that OS is so outdated now (it's based on Vista code).

Purchasing a volume license copy of Server 2012 grants you TWO licenses of Server to be run virtually and you can download whatever version of server you want to use today.

(I also consider it EXTREMELY RISKY purchasing software on ebay that's not in an original, sealed box - maybe this is, but there is a LOT that isn't or is OEM).

Some of the differences as follows :

1. Difference Fair Share CPU Scheduling  : Fair Share CPU Scheduling dynamically distributes processor time across sessions based on the number of active sessions and load on those sessions by using the kernel-level scheduling mechanism included with Windows Server 2008 R2.

Fair Share CPU Scheduling is enabled by default. You can disable this feature by configuring the following registry entry to 0

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\SessionManager\DFSS\EnableDFSS.



Windows Installer RDS Compatibility :

Remote Desktop Services in Windows Server 2008 R2, per user application installations are queued by the RD Session Host server and then handled by the Windows Installer.
