We just barely unboxed the Nexus 10 and we’re already comparing it to its siblings. Just how does it stack up against the Nexus 7 and the first “Google Tablet”, the Motorola Xoom?

Nexus 10

The latest tablet from Google, the Nexus 10, is amazingly light, but very easy to hold. It’s got type of plastic on the back that’s incredibly “grippy” — so much so that you can place the tablet flat on your palm and tilt it over 45-degrees before it skids off your hand. It’s also got a nicely-sized bezel for resting your thumbs (when you’re not trying to impress your friends with the “grippiness test”).

Powering the Nexus 10 is a 1.7 GHz dual-core Exynos 5 processor. Adorning the front is a 10.05-inch display running at 2560*1600 with a pixel density of 300ppi.

Volume buttons are arranged for holding the tablet in landscape mode, so the right button is “volume up” and the left button is “volume down”, which may take some time to get used to, but accurately reflects the direction of the on-screen volume slider.

Motorola Xoom

The first tablet from Google was actually from Motorola and served to introduce us to Android 3.0 Honeycomb (admit it, a cold chill just went down your spine).

Software shortcomings notwithstanding, inside the Xoom was a 1GHz dual-core Tegra 2 processor hiding behind the 10.1-inch display which ran at 1280*800 with a pixel density of 150ppi.

The Xoom is a little smaller in height and length than the Nexus 10, but it’s significantly thicker and much, much heavier.

Nexus 7

The first officially “Google” tablet was the Nexus 7. As its name implies its got a 7-inch display which runs at 1280*800 with a pixel density of around 216ppi. Purring away inside is a 1.2GHz quad-core Tegra 3 processor.

As if to pay homage to its older (but smaller) sibling, the Nexus 10 retains the same type of “stippled plastic” that the back of the Nexus 7 is made of, but only as a strip across the back of the tablet.
