How hard can instant wireless point-to-point worldwide communication be?

Oh right, fairly hard.  I know enough people who have worked in various parts of

It's hard enough that there are a whole lot of suboptimal expensive options with various limitations, and I get to play around with all the extensive sets of constraints to see what works the best for my own needs.

I'm converging on the following approach:

(1) I got the EEE PC, a cheap micro-laptop, for my computing needs.  I can go to any Wi-Fi hotspot and make whatever calls are necessary via skype.  The skype rates are very good.  This is a good option for longer preplanned calls. 
(2) The iphone has very expensive but universal international phone coverage.  It's an extra $6 a month, and the rates for places like Thailand are like $2 a minute.  It seems like it would be good for emergencies -- eg I'm in the middle of nowhere and need to place a call.
(3) Country-specific phonecards can be purchased to stick into local payphones, and the rates will be quite good.  This takes up practically no space and

The alternative is to get a cheap unlocked GSM phone ($60 - $100) and then buy SIM cards as I go through the different countries.  This gets me cheap local rates.  The trouble is that individual country SIM cards appear to be $30-$40 each for only $10 of airtime.  Maybe if I buy the SIM card locally it's not such a ripoff.  However, given that I'm travelling through a lot of countries quickly, I think this local SIM card approach is only useful in a couple of locations.  There are world SIM cards, but their rates aren't much better than the iphone's.  I can't tell if it's possible to pull out the SIM card from this one and insert a country-specific one when necessary.  GIven that the same company sells that phone unlocked for more, I'm guessing the answer is "no".  I might still consider it because I'd rather leave my iphone at home lest it get damaged or stolen.

Update -- apparently there's a "secret" option with AT&T that lets you suspend your domestic cell service if you're traveling internationally, but most customer service representatives won't tell you about it.  (You still pay $10/mo and have to have been a customer for at least 6 months)

Second update -- I've found a much cheaper unlocked GSM phone for $30.  I'm going to get that + an international SIM card (with ~$1/min rates for most countries I'm visiting) + local SIM cards for Vietnam and other countries I'll be spending lots of time in.  According to [livejournal.com profile] maradydd  I can get much better deals on local SIM cards if I buy them in the country I'm visiting.  Then I will save a lot of $ by leaving the iphone at home and dropping the service.
