This Groupon, got things rolling for me. The price point was close enough, that I could get into the world of tablets without the worry that I'd have a super-expensive paper weight if I figured the fondle-slab form factor was not for me.
First impressions, the Thrive is a great device. Feels a tad chunky coming out of the box, but on the flip side, the rubberized back feels very safe and the thickness allows it to be gripped well. One is not constantly worried that it is a matter of time before sweat on your palm will cause the tablet to slip.
Logging in with your Google account means that all of your data comes synchronized right away. All your contacts are in the contacts app, Gmail is up and running and the Photo viewer displays all your Picasa albums - all with no further configuration from you. I know this is true of all Android gadgets, but the effect is scary and giddy at the same time.
Final first impression - the screen. The 10.1 inch display packs in a resolution of 1280 by 800 pixels. The device is powered by the NVIDIA Tegra chip, withe graphics handled by a GeForce card. This graphics focused setup churns out crisp and smooth graphics, without a hint of hesitation. The resolution is so good, that looking at my made-for-web 600x400 crops from Picasa in full screen, made them look - ugly. The capacitive multi-touch screen is very responsive, making the user interface thus far, a real pleasure.
