Really happy to find out that Google themselves are working on a JIT compiler for android. With a bit of luck, older devices will experience 2-3x more speed. For my app Fretter, this will increate the possibility that it will also work on the upcoming low-end devices.
Its also good that it’s Google themselves. There were some rumours about a company that tried to sell it’s JIT technology to carriers, but that would only bring more fragmentation to the android platform.
A talk on Google I/O on this subject will be held around May, so you might expect to see something concrete by that date.
