MS has a lot of good ammunition to fire at Apple when it comes to tablets and productivity. When I see Microcenter selling 7" W8.1 tablets with very fast Intel quadcore CPUs (BayTrail-T Z3735G 1.33GHz Quad-Core) for less than $60, I think MS is going for Apple's jugular. These tablets aren't thin on features either. They have micro card slots, a FULL size USB port (some have 3.0 USB), a mini USB port, mini HDMI, 16/32GB memory, 1/2GB RAM etc. The screens aren't the best but have 1280x800 resolution and are multi-point and IPS. These tablets are basically mini computers for very cheap prices.
I think Apple is going to take a hit in tablet sales if this pricing on feature rich MS tablets continues. Even the tablets with upscale screens will be hundreds of dollars less than Apple's offerings.
