Group Sense PDA (known as GSPDA) has just announced a new Palm OS 5.4-based handset, the Xplore M70.
It looks like this may be a China only device - the QWERTY-less device sports Chinese input and lacks GSM 850 - the resolution is a low-res 220 x 176 display, 1.3-megapixel camera, Bluetooth, SD expansion, and "exciting Palm games." Data tops out at Class 10 GPRS.
I guess this can compete with the Treo in places where you can't get a Treo.
The company, based in Hong Kong, is set up for the design, manufacture and sale of Personal Digital Assistant (PDA) products. GSPDA offers a full range of PDA products including entry-level PDAs, Wireless-Internet-Accessible PDAs and Palm OS Smartphones.
