Comparison chart by Droid Life
DroidLife has posted a comparison chart between the iPad 2 and the Honeycomb competition tablet devices in the Motorola Xoom, the LG G-Slate, and the Samsung Galaxy 10.1.
The iPad 2 seems to be hardware equivalent to the latest Honeycomb tablets. This is not entirely surprising, considering that similar hardware with dual-core Cortex processors have been available for half a year since November of last year in the Viewsonic gTablet and Advent Vega. This removes the hardware advantage Honeycomb tablets had over Apple's products, but the key battle is still software.
Append: Xoom 4G LTE upgrade is not yet available.
