I also bought a LE1600, for 200€ with its specific convertible keyboard.
The convertible keyboard is well-made and includes a trackpoint (a bit too hard and unresponsive for my taste).
When the tablet is put in 'laptop' mode with it, drawing with the stylus is too awkward, so don't count on it.
In this mode, it loses the advantage of being a tablet, so I don't advise people to pick that keyboard if you have any other computer. The tablet has buttons that emulate cursor keys, ESC and ENTER, but that's about it. The secondary button on the pen is not comfortable enough for drawing (IMO), so I sorely lack keyboard shortcuts or modifiers (colorpicker, hold space to pan...)
The fingerprint reader can act as pageup/pagedown, it helps but it's a bit inaccurate.
I'm slightly disappointed by the low pressure sensitivity, it has little difference between "not pressing at all" and "pressing firmly". I think I got more subtle pencil strokes with by Graphire.
The power button can be set to make the unit hibernate, it wakes up in 20 seconds and you can resume drawing, excellent.
I removed the cord that was attached to the pen, as I kept catching things with it; since I only use it at home I don't fear losing the pen.
Character recognition is very impressive for handwriting of words that are in the dictionary, but much less for single characters (typing passwords, URLs, etc)
My conclusion: Exceptionally good for taking notes in handwriting and writing schemas. Better than a wacom tablet for pointing intuitively and immediately where you want. The lack of shortcuts is an annoying limit for many programs. Maybe the best drawing setup would be with a wireless keyboard, so you have 3 devices (keyboard, tablet, pen) with no wire between them.
