Windows 8.1 has arrived.
It's a free update if you've already got a Windows 8 device; otherwise, you'll need to buy a copy of the new OS if you feel it's time to upgrade.
Locally, the retail price is AU$149.99 for the standard Windows 8.1, AU$399.99 for the Pro and AU$249.99 for the Pro Pack (which upgrades standard 8.1 to Pro).
However, Officeworks has the regular Windows 8.1 for just AU$129, which it claims is the cheapest in Australia.
