Summary: I have no problems with this device, it even runs AutoCAD 2015 32-bit! I only have one BIG problem and a possible workaround: If you plug in a MicroSD card, be prepared to find some tweezers to pull that sucker back out. You certainly won't be able to use your fingers to pull it out. They did NOT include a spring-back mechanism to cause the SD card to peep out. I scuffed up an expensive 128GB MicroSD Card and I'm not happy at all.
Summary: Apparently this little guy works extremely well. I don't know what magic Lenovo has used, but the processor pegs out at 2.25GHz with all 4 cores in use and 2.4GHz when just 1 is in use. Dramatic performance improvement over other 8 inch tablets that start at around 1.8GHz and then after a few seconds throttle down to 1.33Ghz. Unexpectedly, this table is 50-70% faster than the Dell Venue 8 Pro in number crunching (benchmarks and video encoding).
Very poor performance, far less than any other device in its class.

Summary: Drastically under powered for an Atom Bay Trail based tablet. I bought this because its supposed to be slightly faster than all the other 8" Windows 8.1 tablets, being a Z3770 chip vs. Z3740. However, soon as you put ANY load on the system, it cycles down to 532mhz. I have TWO ASUS VivoTab 8's and TWO TOSHIBA ENCORE's (the first one, not the 2nd gen garbage) and they both run 100% at 1331Mhz, they never cycle down or over heat and I run them hard, playing an online game,...
