The biggest user share for now is windows users… and they only support Windows XP for the most part officially… is they would have to get certification FOR EACH BROWSER and PLATFORM they want to run the java app on… For instance it has to be certified to run on a particular browser … the problem with any browser (browser agnostic). Medtronic really was required to tie Carelink to IE because of the FDA… The FDA really doesnt like open ended devices and wants the specifications to be set for runninng. Plus you still have hardware driver issues relating to developing on the individual platforms… Using a cross compatible development layer only means the app is easier to build… the problem is the FDA will have to certify BOTH platform versions of the app, and its usually separate for each OS… The esthetic nuances of the MACs do not balance the reduced utility and the higher costs. In the industrial setting, costs and functions determine sales. If I were able to provide more for my customers with Apple equipment, I would have done so. In addition to having a “closed box” Apple charged a hefty premium for the priveledge of owning a MAC. From 1984 until my retirement in 2005, I ran a computer consulting business providing computers and networks to small businesses. So while I understand your predicament, I see the other side of the story.

Niche hardware and software developers continue to provide for the PC only. Even today the descision to buy a MAC severely limits the range of applications to those with the widest of possible audiences. The descision to close the first MAC box doomed the wide spread use of MACs. Apple was the proverbial “dog in the manger.” IBM, on the other hand had an open box and published specifications for others to follow to supplement the utility of their personal computers. hardware, operating system and applications. The first MAC closed off the box (eliminate the slots) and prevented use of other operating systems. If Apple had followed that pattern they would be the dominant supplier today. I had a CPM card in my IIe which ran DOS and DOS applications in addition to the Apple operating system. It was an open box with slots for other cards that extended the use of their machine. MACs often do not provide a large enough market to justify the development costs. The relatively small number of MACs is one deterent and the closed box is the other. There are huge amounts of software and hardware applications that do not run on MACs. MAC owners fail to realize that MACs represent only 10% of the personal computer market. However the newer MAC operating systems have a PC emulation mode which should work. As noted before, the DexCom program is designed for the PC (Windows OS).
