IFA The mainstay of Microsoft's boutique Surface range faces tougher competition as rivals sharpen their act.

Announced at IFA in Berlin with relatively little fanfare – just a line in Lenovo's official announcement – the refreshed IdeaPad Miix 520 is a Surface Pro clone that isn't cheap. But it does look like quality. In fact much of what's new about this year's Surface Pro is replicated. Pen with 4,096 levels of pressure sensitivity? Detachable keyboard with 1.5mm key travel? Yes. But no TrackPoint. Yes. 1TB of SSD, if you want it. Yes. And room for an LTE SIM card, something promised for the SP but has not yet appeared in shipping devices.
