The real point is that now the mobile worker doesn't have to carry a phone + a large microscope. The mobile phone is continuing to replace more and more objects. Radio, tv, camerea, video, internet browser, and now microscope. Many more devices will be adapted to take advantage of the phones computation capability as well as things like GPS, internet etc. BTW, if that mobile health worker has to make a choice between purchasing a microscope and purchasing a phone, they are probably going to purchase the phone.
