I keep my cell phone in "airplane mode" almost all the time. I use VoIP on WiFi most of the time. When I do not have WiFI, I will use VoIP on 3G, but that's less than 1% of the time. Of course, this saves me a lot of money because I don't need a voice plan on my cell phone at all. (I do have the option to pay 25 cents/min and make voice calls, but I have never needed to do that so far. Instead, I pay about 1 cent/min for outgoing VoIP and zero for incoming.)

However, I do not do this just to save money. Here's a reason that is at least as important to me, if not more important: radiation exposure from WiFi is a fraction of the level from cellular radios.

UPDATE: many people are complaining about poor VoIP quality on the Nexus One. My experience is that the Droid handles VoIP much better. See comments below for more info.

I just got my Nexus One today and the first thing I did was set it up for VoIP calling. I'm using it on a T-Mobile data-only plan (no voice minutes needed).

If you don't have a Gizmo account, use an alternative SIP provider. There are a lot of options.

First, get your Gizmo (or other SIP provider) info ready.

This is a nice initiative:

R. McDougall over at climbing-the-hill.blogspot.com was motivated recently to mock the "Linux is not ready for the desktop" articles that are written by people who he feels are "carrying around the self-serving assumption that their preferred OS embodies the only real way to organize a software ecosystem." See his "Why Windows Is Not Ready For The Desktop" post.
 
And to counter the arguments that Linux is irrelevant on the desktop, see  Carla Schroder's post "1% Linux Market Share = 100% Dishonesty". Carla says, "If Linux is such a pipsqueak, why are there such relentless tides of propaganda and deception against it?"
