Now that the iPhone 5 details are public, I thought I'd redo the math for the weight-per-volume using those new numbers.
The iPad 3 is 25.7 cubic inches (in³) and a weight of 23 oz. For 0.89 oz/in³.
The iPad 2 is 23.6 in³ and a weight of 21.3 oz. For 0.90 oz/in³.
The new iPhone 5 is 3.38 in³ and a weight of 3.95 oz. That's a slightly higher 1.16 oz/in³.
Using the predicted iPad mini/air size in inches of 7.78 x 5.31 x 0.28 is 11.57 in³....
Using an iPad density gives a weight of 10.3 oz (292 grams) on the low end and an iPhone 5 density give 13.4 oz (380 grams) on the high end.
Even the higher number is less than the weight of the new 7" Kindle Fire HD (13.9 oz).
I'm still guessing closer to the iPad density and a bit over 10 oz. But even on the high end, its still less than the competition.

iPhone ∞
Go look here. Look at the pictures of the Porsche 911 over the past 40+ years. The details change a bit, but you look at any one of them and you recognize it is a Porsche.
They slowly evolve and improve: more fuel efficient yet more powerful engines, better safety features, better/different finishes.
That's how the iPhone has been and surely will be far into the future. There will be little differences, curves here, angles there, glass vs metal, but the iPhone you'll buy in the future will have that same recognizable style compared to what we have now. You'll recognize any future iPhone as being an iPhone.
Nobody expects Porsche to come out with a completely redesigned and different looking new model every year.

iPhone 5
I'm excited to order mine tonight and get it. Bigger, faster, thinner, lighter. All sounds great. We've already been updating apps to take advantage of the extra screen height.
Thinking about 2 years from now (since the iPhone 5S will surely follow the pattern of updating the stuff inside but keeping the same shell.) I doubt they'd change the resolution again, 1136x640 will be it for quite awhile. But if the "bigger is better" keeps up, they might increase the pixel size. They could now up to a 4.35" screen and still be under the magic 300 dpi Retina number...
But really the Width is what's important, easy 1-handed typing on the keyboard.

Windows 8
I've only used the Windows 8 preview a bit. But from that short time, I think "Windows 8" will be in business books in the same chapter as "New Coke".

Wow, traffic.
One link from DaringFireball and in less than a day this little blog has gotten more page views than it had gotten in the 5 years previous. Nice :)
Better plug
A new connector is coming too.
Apple would know what percent of iPhones/iPads are returned because some little wire in the current 30 pin connection inside the device gets bent and doesn't connect anymore.
If the new connector can go in either direction, then they could have 2 sets of connections (one for each side of the plug) in the iPhone or iPad. If one ever failed, there's a built-in backup and you'd never even know. The odds of both sides failing for the same pin mean whatever the return rate is now, if nothing else changed about how pins connect and bend, this design could cut it to 1/8th that.

Going by this really good analysis...
But Apple's stuff is built more solidly than the Nexus: aluminum, steel, and glass rather than plastic.
Redoing Gruber's weight estimates by calculating the Grams per Cubic Millimeter, the iPod touch is 0.00215 g/mm³ and the iPhone 4S is 0.00223 g/mm³. Multiplying that by his estimated volume comes out with a weight between 416 and 432 grams if it had a similar weight-per-volume as an iPod touch or iPhone.
On this list, that puts it around the Kindle Fire.
Doing similar with the iPad 3, it's about 423,557 cubic mm. For 0.00154 g/mm³ (the iPad 2 gives a virtually identical number, which is another good confirmation on this weight-per-volume method.) Based on those two, it gives a potential weight of 298 grams.
I'd guess that just about 300 grams is a pretty safe estimate, and not far off from the Gruber's original 265 :)
(updated to show correct g/mm³ unit label.)
