I’ve been supporting (RED) since launch a few years back by Oprah and Bono. Apple has been one of the early supporters and now is making its biggest commitment to date. Check out the site for details, and the App Store on your iPhone for the (RED) apps.
I find this fundraising model is interesting. There are products you may choose to buy, not just Apple but other products part of the (RED) family at www.red.org. The choice becomes yours, to purchase the regular product or to purchase the (RED) version, and in the case of Apple at the same cost. As an example, I chose the (RED) iPhone case which is the same cost as the other colours, but I know that a percentage of this case’s sale will go towards the fight to end AIDS.
That’s where I find this model to be sustainable. Allowing people an option to make a change in the world with their purchase.
