The phone is in very good condition, screen is clean from any scratches, couple of dings in the body and the back is pretty much clean. I' ve used it with a case and generally been very careful with it so it's in overall good condition.
the phone is rooted and a version of Android, Cyanogenmod's ROM version had been installed and it's been running great. It is Android 2.3.4 (I think) without the HTC Sense meaning more space for applications (see the case of the Desires and HTC taking some of the Sense out to upgrade the Android OS). Everything works as it should do, WiFi, GPS, maps, camera, flash etc, etc and you can install and uninstall applications to your heart's content.
The ROM came with the in build option of moving apps to the SD (which is included) and therefore having pretty much GBs worth of space for apps storage. If you know your Android then you can check all the above in Cyanogenmod's website and XDA's HTC HD2 pages (loads of them). The ROM was installed with the latest radio ROMs, SPLs, Bootloader, Clockwork Recovery etc so its good to go. I' ve had it for two months and have been constantly installing and unistalling apps.
Battery life with Android is a day, I tend to charge it overnight and use it throughout the day. Because the phone is inherently customisable you can change the profile of its operation i.e. switch between 2G and 3G/HSPA etc etc. I' ve used it heavily, with maps, calls and emails and got easily through the day. In any I have a backup battery so no worries with running out battery.
Remember if you want you can always re-flash Win 6.5, or a different flavour of Android.
So, you get:
Phone as described above, running Android 2.3.4
Orginal charger and cable
8GB micro SD, already on the phone
Additional battery, same as HTC's, bought from Expansys (I think)
HTC Leather case, flip ones
All in all a good package I think, and I would like £95
