The Citrix Mobile Console allows you to manage your Citrix using mobile handheld devices or mobile phones which support the Citrix ICA Client on them. (Windows CE, Mobile)
Essentially it's an adapted version of the Citrix Management Console (CMC) you can access from a mobile (small form factor) device.
Whilst this is quite a cool idea and geekie concept the novelty wears off pretty quickly. The small form factor screen may be great for a quick check of the email or calendar, but using it for more than a couple of minutes can really affect your eyes and your sanity.
That being said there are scenarios where the Citrix Mobile Console could come in handy maybe at 3am in the morning when out, and that all important support call from your boss comes in, getting the mobile device out and connecting in from anywhere (in theory) could be quick and provide administration support as required and the reduced need of carrying all that bulky laptop kit.
