Are you sure you can return it within a month? Or is it 14 days (in Canada we only have 14 days for computers).
But yeah. If you want something that just works: iPad, if you want something buggy but fully featured: surface pro. If you want a hybrid of these things with cheap build quality: android. If you suffer from mental illness: surface RT
Umh.. stereotypes much?... Did you even listen to the OP's needs?
If you need a portable device for drawing I don't see that many alternatives to the Surface Pro 2.
Anyways, yes there were some severe issues but in first line those were only related to the December firmware update whichw as pulled soon after. No device you will buy now will be affected by that!
Of course there's the (if you ask me, very little) possibility that MS does crap again, but losing trust in them that easily leads you onto the route of unhealthy stereotyping, in my opinion
Not to mention that most people also survived the faulty update too and the drawing capabilities weren't affected at all.
Now to the suggestions you asked for.
A non-reflection screen protector is said to increase the traction of the pen on the display a little. The screen i scratch-resistent (to a degree at least) so I wouldn't say that's absolutely necessary.
If you really want higher traction, almost comparable to the one of a real pen then you can get those: Soft/Black Nibs for Bamboo Stylus Feel (CS-300/CS-400) | Wacom eStore - official Onlinestore
(they should be available in germany too, but for some reason the site automatically jumps to UK although I'm in germany myself >< )
Those are said to be able to replace the nibs in the Surface's original pen and are far softer, resulting in higher traction. Of course you can also use other pen's like the one mentioned above. Every "bamboo" or "feel" pen is supposed to work. There's a better description of matching pens here: TabletPC Compatible Wacom Pens (Work with Surface Pro)
Read around the last sites.
Anyways, I got used to drawing as an amateur with the standard pen easily so I'd say its all depending of what you can accomodate to.
Whether you need a keyboard like the Type Cover 2 depends on how youw ant to use the device exactly. If youw ant to use it as a highly mobile laptop occasionally, I think the typecover is definitely worth it. It's expensive.. but works good enough for typing.
The touchpad is something else unfortunately but why use the touchpad if you have a touchscreen?
For drawing that keyboard isn't the eprfect solution since of course it's between you and the screen... So if you want to handle you art software like PS with keyboard shortcuts it might be an option to get an external bluetooth keyboard which you can place wherever you want.
