You won't have to wait until March to get your hands on Lenovo's 10-inch Miix 2; much to our surprise, the budget-friendly convertible tablet is already on sale. Just be prepared to pay extra for early access. The company is offering only higher-end versions of the Windows 8.1 slate, which currently starts at $699 for a WiFi model with 128GB of storage. The promised $499 variant isn't listed on Lenovo's site as of this writing. While it's hard to complain too much about the higher price given the unexpectedly quick launch, those who want the cheapest edition of this mid-size Miix 2 will have to be patient.
