[Disclaimer: I've not used it much] The thing is that a keyboard that fits some people may not necessarily fit others.
We are shaped differently and have different typing styles, typing postures, and different problems.
Thus, while the Alice layout may be great for some users, it may not necessarily be great for
you — and only
you can figure that out.
There are two major ways that wrists can be angled unnaturally on a traditional keyboard.
• Ulnar deviation: Rotating the wrist outward. (especially the left wrist)
• Forearm pronation: Holding the wrists rotated too flatly against the desk.
The Alice layout can help some with avoiding the first point, but it helps nobody with the other. If forearm pronation is what affects you more then you'd be better helped with a keyboard that is "tented", i.e. having the left and side halves leaning sideways to form a "tent" shape.
You'd might want to check out the
Type-K, which will have the Alice layout
and 7° tenting. (I think the Microsoft Natural series had 8°, but maybe varied)
Edit: There are DIY options
Slice. and
BuzzSaw.
Unfortunately the keyboard enthusiast community can be a bit opinionated at times.. Some "purists" might yell that the Alice (or even the Type-K) would not be ergo at all because it is not split into two pieces - and therefore not adjustable to fit
everyone. Others might yell at you to get a columnar or ortholinear ("ortho") keyboard (because that is what they use) but I think those would require
more tenting to avoid forearm pronation than with staggered keyboards.
