Pam, thanks for the insight. Satellite phones can definitely be used for internet connections. For many examples try this google search: http://www.google.com/search?q=%22satellite+phone%22+laptop There's no necessity to use a Solo computer for this ... all of the satellite phones that provide data will work with any laptop. There's definitely a difference between VSAT and satellite phone. A VSAT link is like a leased line ... it's a permanent connection to the internet that you lease by the month. For the period of the lease you may use it as often as you like, you can saturate the connection 100% of the time if you like, the price is fixed at a monthly rate. With satellite phone you're paying ... buy the minute. Probably a couple of dollars a minute. So, if your use is sporadic and for very short periods at a time, it may be cheaper than VSAT. That said, VSAT links are usually in the range of $100-$300 a month depending on where you are, that's for the slowest connections of VSAT which are still just as fast as the fastest satellite phone. Satellite phones max out at 144kbps but are more typically 9.6kbps, or 56kbps. > As a potential purchaser I know I won't get hold of one until someone in > Africa sets up a small, locally financed company, to do small scale > assembly (about 100 units a month).

I hope you succeed, but I have to say I'm doubtful that the Solo computer will ultimately prove to be cheaper or better than a laptop. Keeping in mind that a local economy can develop around laptops too ... maybe not building but selling, servicing. And most of the world's laptops are built in just a few factories in Taiwan anyway ;-) simon -- www.simonwoodside.com :: www.openict.net :: www.semacode.org 99% Devil, 1% Angel ------------ This DOT-COM Discussion is funded by the dot-ORG USAID Cooperative Agreement, and hosted by GKD. http://www.dot-com-alliance.org provides more information.
