No - not a typo or flashback!
Microsoft have announced the 'Surface 3' (as opposed to the 'Surface Pro 3' that we know well here) this one comes in 64gb and 128gb versions and is $499 and $599.
It runs FULL windows 8.1, so in theory can do what we need. But just has an Intel Atom processor, so will be much less powerful and slow to build previews etc. Not sure if that makes it unusable or not, but thought it worth sharing. It should have a longer battery life from that lower power processor.
I still hear rumors of an iPad Pro, but we can be confident it will come with a high price tag, and most likely a single funky connector that no one else has used as yet <sigh>
