"The other good news is the boasting rights this will give you over owners of rival Android hardware"

Oh goody, another opportunity to act like a complete muppet. People "boasting" about how much better what they bought is than something else someone else bought are in dire need of a smack around the head with a wet cod.

Can anyone tell me if the power passed through the 30 pin connector has been increased over that of iOS 4.2.1? It used to be that there was enough power to allow me to connect my Logitech DiNovo wireless keyboard's dongle through the Apple Camera Connector's USB port to run the keyboard. With iOS 4.2 onward, the amperage output was lowered (to 20 mah IIRC) so the keyboard could no longer be used.

Testing the following with Motorola Xoom and Galaxy Tab using Sunspider 0.91. It's awesome to see how much better Safari is getting. Apple must be pumping some money into development. The good news is that all of these benchmarks improve every year with browser improvements:

Galaxy Tab (firefox): 2697 ms
Motorola Zoom (ff): 1787 ms

Don't believe any sunspider benchmarks older than 6 months - this is a variable benchmark that has been improving with *every* update to a browser, including incremental ones.

The JavaScript engine in 4.3 really is a whole lot faster than it was before. I've already updated my iPhone 3GS with the 4.3 GM and tried SunSpider both on that, and on my first-gen iPad running 4.2. The 3GS is now about ~1.5x faster in that benchmark than the iPad, while the iPad has an ~1.5x faster CPU. So with ~2/3 of the CPU speed it gets ~1.5x the performance, which means the JavaScript engine is over 2 times faster than before, which seems to be inline with this article :-)

Original iPad running iOS 4.3 GM gets around 3200ms in SunSpider compared to 2100ms for the iPad 2. However, it's important to note that SunSpider is not multi-core enabled benchmark while web browsers are, so performance should be much faster in the real world than what the benchmark reflects.

Hope they fixed the image load memory-leak!

Cool! I only hope that Apple does not forget the old hardware too quickly. I would hate that my current iPad be relegated as a "browse only" machine.

It seems that the 3G iPhone is a thing of the past, but having recently given away my original iPhone it's easy to forget that the 2G was from less than 4 years ago, and the 3G is about 3 years old. For the full price we end up paying it seems unfair that they get old so quickly...

Nice!

The updates that have been so far detailed will work together to make for one very impressive second generation iPad. The additional speed or other wise good performance should attract many of the current owners. I know that in the various forums one gets beaten upon when they call iPad 1 slow but the new model will clearly demonstrate just how pathetic "one" is.

In any event I look forward to more extensive testing. Not that imam big fan of benchmarking, but rather I hope third party data will educate those that don't understand the importance of RAM, multi core processors and other goodies.

I got 4094ms on my 32gb iPhone 4 running 4.3GM.
