It can only run "Metro" style "apps." Benchmarks matter not in this case. It does come with Microsoft Office though. Now, a Tegra 4 is a capable chipset: quad core 1.8Ghz, 2GB RAM, and a decent GPU - however, like I said, it can only, and will only run Windows RT apps because it's not an Intel-based processor, it's an ARM processor, like found in cell phones (I will be happy to write a "Hello World" program for you in Visual Studio, however). The Google ADT-1 (Android TV developer console) runs on a Tegra 4 SOC, and it kicks ass, but like I said...no support for "real" Windows due to the architecture.
The people who buy it are generally happy, but they know what they're getting into ahead of time. I was going to jump on the offer until I saw it was a Surface 2 and not a Surface Pro 2 (which go for around $600 base). Honestly the 32GB should have raised an eyebrow after the initial oversight.
It might be possible to somehow get Chromium OS or a version of Linux (I would imagine there's an ARM-based version of Ubuntu out there) installed on it.
