I ordered a Dell Venue 11 Pro over Christmas and have had over a month to play with it. In terms of context, it was intended to replace two relatively ancient mobile devices; a BlackBerry Playbook (couch browsing) and a Penryn Dell Latitude D630. I mostly use two desktops at home - one attached to my TV and one at a desk.

Key specs:
Core M 5Y10 (up to 2GHz)
4GB memory
128GB SSD (made by Sandisk)
11" 1080P IPS touchscreen
Intel 7265 Wireless-AC
Also bought keyboard+battery attachment, and stylus

General performance-wise, it slides in between my desktops and the D630. My old laptop (T8300) often struggled with complex webpages and the new tablet does not. I am used to SSDs in all my devices and while not top notch, no complaints about the Sandisk SSD. Part of it might be the eMMC interface.

I haven't yet tried any 3D stuff. I only have IGPs since I no longer play many complex games.

The wireless-AC is amazing. My DIR-615 broke over xmas so I bought a new TP-Link Archer C7, and out of the box it is possible to transfer at 300-350mbps which to me is a decent showing. I haven't bothered tweaking anything yet.

Battery life is good. My conservative estimate is about 7 hours but with the screen and wifi on at idle, battery bar shows about 3W usage meaning that the 35WHr battery should last at least 10-12 hours just sitting there.

Connected standby was mixed. My expectation of a tablet is that if I don't use it but leave it on, it can go for days before dying. Initially, I had trouble getting it to last more than a day. I tried reformatting/reinstalling/driver tweaks and nothing worked; it used about 1.5-2W in connected standby and you could feel the back of the tablet was warm. After the A03 BIOS update, it seemed to be better. I don't think it quite meets the expected standard of 5% of battery over 16 hours (implying 1.8WHr for 16 hours, or 0.13W), but I've gotten it down to about 0.3W, meaning it can sit there for 100 hours or about 4 days, which is pretty good.

With the keyboard and secondary battery unit, the capacity nearly doubles to about 65WHr meaning a week sleeping, or at least 2-3 days of productivity.

Overall, I am quite impressed. The battery issue annoyed me and I wasted lots of time trying to diagnose, but it seems to be adequately resolved. The fanless design is great, and the system is fast.

I would gladly run benchmarks if anybody wants to perform a specific test on the CPU, IGP, or SSD.

Adding to this, I happen to have the last gen model (i5-4300Y, 256gb SSD 8 gigs of ram) and I would be more than willing to run benchmarks to compare to the newest model as well.
