According to Slashgear, Citrix is hoping to change the way businessmen travel. The Nirvana phone is a low spec device with thin client like capabilities. Instead of sending someone out of town with a laptop, a company could give one of these phones, which could be used to access a virtual desktop back at work. The virtual desktop could be used on the phone itself, but preferably, the user would find a monitor with a Bluetooth mouse and keyboard to attach to the phone, making it a fully usable machine.
The phone will connect to a virtual environment via a Wi-Fi or 3G connection and will be able to output full HD video to a connected display via an HDMI or VGA connection. The platform requires, at least, an ARM 528MHz processor with 256MB of ROM and 192MB of RAM. Assuming the platform is implemented correctly, it would still allow phone calls and other basic phone functionality to work while using the Nirvana platform.
If employees frequently travel to places that have spare monitors and Bluetooth enabled peripherals (such as an out-of-town location of the company, or home), this platform may become the ideal way for their companies to keep them connected while away from the office. The platform will have the ability to run on Windows Mobile, Android, Symbian, and perhaps even iPhone OS. Citrix is currently working with certain, undisclosed, handset manufacturers to try and get Nirvana into the market by the end of the year.
