Wrong question!
Your review wasn't so bad, once I had read the whole thing, but the first page had me incensed. Is it a phone or not!?! Bloody hell, just because it's a Nokia product doesn't mean that the issue of a phone ever has to come up!
It's not a phone, it was never meant to be a phone, and nobody who's looking for a small but not miniscule internet tablet for browsing and handling e-mail while traveling would ever need it to be a phone. My tiny cell phone works just fine for phone calls, but I would never use that damn small screen for either internet browsing or e-mail. (Yes, I'm over fifty, so what?)
To get back to the point, it's called an internet tablet for a reason. It's aimed at people who travel a lot but don't necessarily need their laptop with them. I want to be able to browse and check my e-mail, but that's about it. I need a reliable connection, and my cell phone with bluetooth provides that, because I am often in places with cell phone coverage but not broadband. I also need a larger, more crisp screen than I get on my cell phone. I am a developer, so a platform that I can develop on, that doesn't make Bill Gates any richer and that doesn't devote more than half its cost to the OS is fine with me. Finally, I need a little speed, and enough memory to handle large numbers of e-mail messages and rss feeds. The Nokia has all these things. (And by the way, did you notice that the N800 has TWO slots for memory cards, not one?)
So stop trying to treat it like a phone. Cell phones as now configured will soon be obsolete anyway, when people figure out that they can carry their computer in their pocket or purse, and talk on the "phone" as much as they want on their bluetooth headset.
I hope that when Nokia comes out with the next product in this line, you won't still be trying to compare it to a cell phone. I also hope that you'll check around before you call this line unreliable. I've been trying mine out for weeks now, and it's never crashed.
