A few days ago I finally installed SAPGUI 6.40 for Windows on my laptop. I upgraded from 6.20 patch 47 and the installation went very smoothly and pretty quickly – less than 10 minutes on my 1.5GHz Pentium-M (I didn’t bother running SAPSweep beforehand). One thing to be aware of – the upgrade only upgrades already installed functionality. If you want the new stuff (eg Adobe Designer), once you’ve upgraded, you need to run the setup program again and install any missing components that you need.

The performance seems pretty similar to 6.20 and with 7 sessions open to two systems, memory usage was at 31,440K according to Windows Task Manager. New with 6.40 is the ability to have the GUI use the Windows shell visual style if using XP or Server 2003 (I still use the Streamline look and feel which debuted with one of the later 6.20 patches)

For more info on the new features in the 6.40 GUI, check out OSS note 710720.

Overall, seems like a worthy, fairly painless upgrade.
