Hm, yeah, to an extent I'm feeling sort of the same way.

I love the tablets but found that most of the things I use them for daily are things I could actually do with a smartphone and dispense with the extra device in my pocket; as such, I recently acquired a G1. It definitely does lots of things less well than the tablets -- but not the things I do multiple times a day, necessarily. Until I get service for it in a week or so I'm still doing the two-device routine, though.

At any rate I've pretty much resolved to sell my n810 -- I love it, but since it has more resale value I should part with it, and then retain my N800 for all of the cool stuff these devices can do. Its text entry isn't as good, of course, and it's a little bulkier, but if I'm using either my phone or my computer for text-heavy stuff like email and using it mainly at home, it seems handy to keep around.

Plus they're just fun. It's a cool platform.
