Google debuted the second iteration of its popular Nexus 7 tablet today at a San Francisco press conference, inciting excitement amongst fans of the Android device and plenty of comparisons to Apple's iPad mini. Of course we're most interested in how this second-gen device might fit into a photographer's workflow.

First off, the 7-inch screen is sharper, making the new Nexus 7 an even better portable portfolio and image editing tool. The resolution is now 1920x1200 with a pixel density of 323 ppi (the old model was 1280x800 and 216ppi), which should let you show off photos nicely, or get some quick editing done on the go using a compatible app. Some of our favorite photography-related apps for Android tablets should work even better on the new model: Dropbox for photo storage and management, and both Snapseed and Photo Editor by Aviary for mobile photo editing.

A new primary 5-megapixel camera won't replace anything else you're shooting with, but might do in a pinch, and is certainly better than only having the 1.2MP front-facing camera available on the first-gen Nexus 7. A good capture app like ProCapture or Camera Zoom FX could make the most of the new 5MP camera.

It's even easier to take with you at 2mm slimmer and 50 grams lighter.

Google says the battery life is longer: Google promises more than nine hours of HD video playback and 10 hours of web browsing or reading. Total battery life of the old model was listed as nine hours, but this estimate may have been high according to user reviews.

It's powerful: A 1.5 GHz quad-core Qualcomm Snapdragon S4 Pro should keep the tablet speedy and responsive even when handling large files.

It's also the first device to ship with Android 4.3, the newest version of Android.

Google's new Nexus 7 will come in a 16GB Wi-Fi model ($229), a 32GB Wi-Fi model ($269) and an unlocked 32GB 4G LTE version ($349). The Wi-Fi models will become available first, starting on July 30 in the U.S. Availability in additional countries will follow.

There's a lot of comparisons to be made between the new Nexus 7 and last year's iPad mini, and currently the Android model appears to offer more bang for your buck:
