I have a Motorola Xoom that I originally purchased for work however it quickly became just an entertainment device. I found it too slow to type on screen in meetings, our large organization has no outlook integration on mobile devices (vpn only) so I was redirecting through gmail at times. I can't open various office files properly, no Autocad, Visio or other similar type file access. I'm not a fan of having the laptop blocking me from others in meetings so it was a return to the trusty notepad and pen. That was until..
The Surface Pro 2, a device that has totally changed the way I work. I retired my laptop and run the SP2 on dual external monitors, in the dock with external keyboard and mouse at my desk. On the road I use the attached keyboard and wedge mouse. If I am at a customer site for long I'll plugin to an unused workstation monitor for an extra screen. I have all my apps (Autocad, Visio & custom business apps, Juniper VPN) and can open all files natively, edit and email. I also develop heavily in Linux so I have VM's (Debian and Suse) on hand. At some point I'll play around with dual boot on the device.
Probably the biggest change has been use in meetings. The pen input is superb I hand write all my notes, draw diagrams and file away in One note. There is no impersonal laptop blocking me and others nor am I frantically typing away while someone is talking. I also have access to every file, email, note etc I need.
I really like the little details like the fine point pen input, the touch is disabled when the pen hovers over the screen so you can rest your palm on the screen. The rear camera is angled up so you can have the device upright yet still record presentations.
On the flip side MS support leaves much to be desired for and a few of us have gone through some painful sleep/hibernate issues on the device since the Dec firmware patch but that seems to be ironed out since the Jan 14 update (for most it seems not all).
