From most expensive to least expensive, here is what you need to know:

The 7610 has the ability to capture a color with the camera and then apply that same, or roughly the same, color to the wallpaper and keypad of the device which I find totally freaking awesome and it reminds me of the Nokia Morph video. TV out is included along with a 3.2 megapixel camera, FM radio, quadband GSM/EDGE, 2 inch 320×240 pixel 16 million color screen and 860 mAh battery. It can be had for 225 EUR in Q3 2008 and it is pretty small at 98×48×15 mm weighing only 99 grams.
The 7510 is a clam shell device (pictured above), with a 2 megapixel camera that has a technology called “NIPS” which I have yet to figure out what that is and it comes out in Q4 2008 for 180 EUR. It has the same open source webkit browser that S60 devices have, 2.2 inch 320×240 pixel 16 million color screen, quadband GSM/EDGE and 870 mAh battery. Pretty small at 92.5×46.4×16.7 mm, but a bit fat don’t you think? Weighs 124 grams.
The 7310 (can’t use 7410 since 4 is a bad number in Asia) comes out in Q2 2008, which ends in 3 days, for 155 EUR and it manages to squeeze in TV out and a 2 megapixel camera. You get a 2 inch 320×240 pixel 16 million color display, triband GSM/EDGE, 860 mAh battery all in a 106.5×45.4×11.95 mm body that weighs only 83 grams; crazy light.
7210, the cheapest at 120 EUR coming out in Q3 2008, has a 2 megapixel camera with one click upload to Flickr! This is the first device I’ve seen Nokia quote the weight without the battery installed and I just want to find out why? It’s not like people carry a mobile phone without a battery inside now is it? Anyway, 69.8 grams without the 860 mAh battery that is supposed to come inside the box, triband GSM/EDGE, 2 inch 320×240 pixel 262,000 color display and Bluetooth 2.0 with A2DP. Surprising at that cost.
