I'm using this device to monitor and trade stock online. No need to subsribe or pay charges for pda stock trading software eg.. RM50 permonth coz
the device i use run on full WIN XP and full fledge IE browser.

I called it a "Brick" coz its size like a brick..
It got alot juice also.. battery lifes can go up for 8hrs++ on hsdpa connection
I bought from SG Sim lim.

If you are loaded,,.. den get the OQO E2 HSDPA.. its really a cool gadgets.
