Summary: They seem to like it overall, for example they liked that it
booted much faster than Windows, but complained about some features
documented to be missing:
* ThinkVantage Active Protection System.
* ThinkVantage Access Connections for SUSE Linux
* ThinkPad Configuration for SUSE Linux
* ThinkPad Power Manager for SUSE Linux
* Wireless WAN Adapter
* ThinkVantage Button
* (Intel Graphics System) DVI Output
And they couldn't get Xen to work.
I found SUSE as an option on their custom builds a week ago, with a
four-week delay, but it has since disappeared, even though their T-series
blurb mentions it being an option still. It was an option alongside
windows in the customization, and it was the least expensive OS option.
