Similar to HTC Wizard, it seems that Artemis has built-in the TCS3500 chipset, which is manufactured by Texas Instruments. The key advantage of TCS 3500 is all the wireless technology support (taken from the TI datasheet, link bellow):

• Complete pre-FTA certified, smartphone EDGE Class 12 reference design
• Applications including MPEG-4 video and Windows Media™ video, MP3, 2.0 megapixel camera,
• Software compatible with TCS2600 GSM/GPRS chipset
• Modules available for camera, A-GPS through TI’s TGS5000 chipset and high-speed WLAN through TI’s TNETW1230
• TI’s highly integrated BRF6150 Bluetooth wireless technology chipset based on TI’s patented DRP architecture
• High-level mobile OS support, including Symbian OS™ and Nokia S60, Microsoft® Windows Mobile™, Palm OS®, SavaJe OS and Linux

To make this post complete, it is important to say that the TCS3500 solution also includes the OMAP 850 CPU (datasheet available here).
