If you can check the price on the p1610 (usually too expensive to even consider) I'd appreciate it.
If it around 500 Euros, I'd jump right in!
I would also be interested in the U810/1010/8240 for those prices - my only "issue" with that one, is that - although really handy and highly "wanted", and nearly perfect; it has just a couple of thing I don't like:
The worst being the keyboard layout which is kind of stupid: you have to press the "FN" key to have cursors keys.

(With a decent layout it would be just perfect)
Maybe we can get a workaround in software, to remaps the keys... but I don't what those engineers were thinking about when they designed it.
