ViewSonic has kicked off the Showstoppers festivities at Mobile World Congress with a couple new tablets: the ViewPad G70 and E70 (pictured left and right). The twin tabs are specced just about the same save for a couple minor differences in bells and whistles and the E70's 150€ (roughly $200) price tag ringing in at half of the G70's €300 tally. Both tablets will ship running Android 4 ICS, feature 7-inch displays -- with E70 getting an 800x480 version and the G70 a 1024x600 unit -- 1Ghz Cortex A9 CPUs, and 3300mAh cells. The E70 should start shipping by April this year and the G70 in late June, and we're pretty sure ViewSonic will need all that time to polish both of these up -- no, not the fingerprints, though they are magnets. The device's response to touch input wasn't particularly accurate and the interface was very lagged when using it. Unfortunately we were also unable to ignore how weak these two displays were, and on a device that uses the screen for its principal point of interaction, that's a dealbreaker for us. Here's hoping these two get a buff and polish before launch time. Hit the gallery for some pics.
