It's the question consumers ask most about any new tech gadget: "Should I get this now, or is something better coming along soon?"
For buyers of Amazon's Kindle Fire, we now have the answer: You should have waited.
Google's new Nexus 7 is aimed directly at the Kindle Fire, the 7-inch color tablet that was the runaway hit last holiday season. The Nexus 7 obliterates every reason for buying the current Kindle and sets a high bar for whatever Amazon comes up with to replace it.
The Nexus 7 is Google's first foray into selling a tablet under its own brand. It costs $199 for a model with 8 gigabytes of storage, same as the Kindle, or $249 for 16 gigabytes.
At 7.8 inches tall and 4.7 inches wide, the Nexus 7 is compact enough to slide into a jacket pocket. A rubbery, textured back makes it easy to grip. Like the Kindle Fire, it works only over a Wi-Fi connection; while the screens are the same size, the Nexus 7's has a resolution of 1280 x 800 pixels, compared with the Kindle Fire's 1024 x 600.
The Google tablet also has a more powerful, quad-core processor, twice the internal memory and better battery. At four-tenths of an inch thick and 12 ounces, it's also thinner and 18 percent lighter.
Go down the list of standard tablet features, and the Nexus 7 wins every one. Camera? None for the Kindle; the Nexus has a front-facing camera and microphone for video calls.
Bluetooth? The Kindle doesn't have it; the Nexus 7 does.
