I'd love to see Tom's review and compare 8- and 10-inch Windows-based tablets, especially those that come w/ docking stations.
I've had my hands on both the Dell Venue 8 and the 10" ASUS Transformer T100 Book. Of the two, I actually prefer the ASUS. With its larger screen and the addition of an included docking station, it simply felt like a much more complete and easier to use device. The only slightly greater price tag on the Transformer T100 Book pretty much seals the deal. (That is, unless I lived much closer to a MicroCenter, which has been selling the 32GB and 64GB Venue 8 models in its stores for $230 and $300, respectively.)
This Iconia W4 has some well-established and steep competition.
