apple has been secretly compiling binaries on intel chips of osx since 10.1.
macs development package Xtools 2.1 provides the option to compile universal binaries for both versions of the operating system.
for older mac based applications there is a light weight but powerfull emulator called rosetta.
2006 is the first mac machine to ship with intel processors
leopard is the next major release but no hints were given
osx widgets have gone nuts with hundreds of widgets being made and some of them are very good.
umm yeah theres a video keynote address on apples site if you want to watch it.
