I've had a 770 with a ThinkOutside Stowaway bluetooth keyboard for about two years now. It took me a while, and quite a bit of tinkering with it, but for the most part, it has served me well, as long as I accept what it is and what it isn't. What it is not, is a PDA. I wanted it to provide the PDA like functionality that my Psion5 did. In that regard, it failed miserably. Once I got past that though, I've found some things I absolutely love about it.

First, pairing it with my Nokia 6103 phone via bluetooth is a snap. So, I've used it to download wind data while sailing on the great lakes. If you're within a mile or so of shoreline, cell coverage is generally good, especially near Detroit where I sail. So, it's made a great sailing computer, as the screen is bright, readable, and the 770 is so much more convenient when you're getting knocked around in wind and waves.

Second, with the folding bluetooth keyboard, I use it to edit code when I'm sick of sitting in my home office. The two are small enough together that they both easily fit, along with my iPod, into a small, Franklin Planner sized case that came with my Toshiba Libretto I had 10 years ago. Another plus, I can use it to remote desktop into my Mac and my (dreaded) Windows machine when I need to compile the code I'm editing for work.

Of course I give up a few luxuries when I'm doing this, and some of the features are a bit quirky, but all-in-all, my 770 keeps finding new ways to be useful to me.

As a final note, I have a non-geek friend that has a N810. He's a stock broker, and he's addicted to his N810. It's replaced his laptop completely, since what he mainly uses it for is checking quotes, surfing the web, and writing quick messages. He couldn't imagine replacing his N810 with a Windows Mobile device, because in his words, "Linux just works".
