Lenovo's recently unveiled 2-in-1, the Yoga Book, is available in Android Marshmallow and Windows 10 Home versions.
Reviews have been mixed, with some praising its look and feel, but some considering its capabilities not up to scratch. Its Intel Atom processor doesn't provide enough power for a workhorse device, they have argued.
The Android version costs US$500 and the Windows version goes for $550.
The Atom processor "was a cost-saving measure, because Lenovo hasn't yet shown that its customers will shell out top dollar for a device with a sixth- or seventh-generation Intel processor," said Eric Smith.
