Does it work OK with an SD card? I've got the 10" Yoga 3 Pro Tab and SD usage is incredibly sluggish even for photos or comic reading. The rest of the tablet is great, but if you try to use the SD, it shits a brick. Tested with multiple sizes/makes of SD.
I know @Velocio rates Lenovo laptops, how are their tablets?
