After some years of "inactivity"with OS/2 (have the 4.5) I tried to seek some info about the eCS.
Welcome back. This site should get you some information
http://www.ecomstation.com/I mainly looking if the new eCS offers/has Bluetooth support.
Unfortunately, no. Bluetooth is one of the things on the wish list, but nobody has taken enough interest in it to create the appropriate driver(s). Other things are far more important, and there are not enough qualified programers to go around.
