It's funny you should ask... I actually own an SP3 and was considering giving animating using it a go today! It's a cool device, but for the premium cost you really have to want it over a standard laptop or ultrabook. If I actually animate I'll report my findings.

I used my SP3 for the whole of my THAC XII entry and it worked really well.The size was great because it meant it didn't get in the way. I had a USB hub connected with my blue yeti, c920, number keypad, mouse and flash drive and all worked fine. If you get one make sure the USB hub is externally powered rather than 'bus powered' though otherwise webcams and mics start playing up.

All my software worked fine too including, despite its age Helium Frog (after applying my source error fix) and when it came to editing the video rendered very quickly.

I'd say overall it worked perfectly well, all be it like any other Windows machine. For Surfaces the type cover is an absolute must, I have it attached 95% of the time.

I actually coudn't justify the price of the Surface Pro, when you consider the extra price of the keyboard, extremely small HD and single USB port.  I bought this instead:

I got so much more for the same price.

It's a laptop AND a tablet and I'm loving it.  I've got it in my studio, plugged into a second monitor (to save my eyes).  I can fold the screen all the way back so it is flat on the desk and use the monitor to do capture.  I can still glance at the laptop screen (despite the odd angle) briefly to do other desktop operations (save files, look for voice files etc).  It struggles with some larger projects (I'm talking 10+ minute projects - not THAC projects) but not a single regret.

Get a bluetooth mouse for animating though.  Hard to do so with a touch pad (but not impossible).

That asus has an i7 duel core and it struggles with Corel Pinnacle.  I use stop motion pro eclipse and it captures and plays back fine but if I do some quick shuttling between frames in edit mode then there can be a one or two second delay updating to the current frame.

Not saying what is good or bad - just pointing out with that asus hardware I linked on a fresh Windows 8.1, some editing is asking a little too much.
