The ipad version (asetniop.com/ipad or asetniop.com/ipad.html) has been updated to allow for handwriting recognition of both numbers AND symbols.
Characters recognized in the N pad (below the yellow helper bar): 0-9, slash, backslash, dash
Characters recognized in the I pad (below the orange helper bar): ! @ # $ % ^ & * [ ] { } _ / \ | = + < > ~ £ € ¥
All symbols must be drawn with a single stroke. Characters that consist of multiple strokes are generally recognized by the first part of the symbol. Some special cases:
4 can be drawn in a single stroke (like a lower-case “y”) or as the first half of the numeral (like an upper-case “L”)
7 should not be drawn with a crossbar
! can be drawn as a single upside-down triangle (▼)
# must be drawn as a simple square (■)
$ will be recognized when just the “S” part is drawn
% will be recognized when the top-left circle and the slash character are drawn as a single connected character
* will be recognized when drawn as a five-pointed star
= must be drawn with the two lines connected, as a “z”
+ must be drawn as a single line by tracing downwards then looping back to the left to begin the horizontal stroke
£ may be drawn as a simple “L”
€ may be drawn as a backwards “3″
¥ must be drawn as a backwards lower-case “y”

Don’t you guys remember how much people loved writing e-mails in PalmOS? (That’s sarcasm; people couldn’t even reliably remember how to draw 4s, 7s, and Ts since it was they, and not the device, that had to do the learning.) Why not keep your focus on the defining, uniquely appealing parts of your input method for now? The mode changing key combo is a neat idea and keeps the input method consistent. Remembering which box to draw a $ in and that you shouldn’t try to add the vertical bar seems a little jarring in contrast.
The layout flip is still available; just use the “devil horns” code (think “number of the beast” as a mnemonic) – this is actually preferable when working with primarily numbers/symbols (i.e. in a spreadsheet application). The handwriting recognition is meant to simplify entry for when you only want one or two numbers/symbols, and also make life a little easier with gesture-recognition applications (like the LEAP). Future versions will include a neural network to learn your personal style of what your numbers/symbols look like, so as long as you’re consistent in how you draw things, it will only need to learn things once.
