One of Wyse's many announcements from Citrix Synergy 2011 San Francisco was their new line of T50 thin clients. These are the first ARM-based thin clients they've offered, with a starting price at $239. Since they're not x64-based chips, they run a version of ARM Linux instead of ThinOS. But unlike ThinOS, the T50 does have a local web browser.
Is this Wyse's answer to "Why don't you make a cheap thin client?"
