I'll throw my appreciation for the iPhone and iPad in here. I've been an enthusiastic user of the iPhone through 3 different versions now, each better than the last. Being exclusively an Apple computer user, it all just works together. None of this virus checking, malware protection, constant system updates, OS crashes etc. The foundation of it all is UNIX, whether it be a phone, iPad or Mac. A proper, secure, multi-user, multi-tasking operating System. Add to that the Aqua GUI of the Mac and the iOS GUIs on the phone & iPad, together with some very innovative industrial designs, and you have a winner. They do cost a bit more, and they're not absolutely perfect, but do you want a Mercedes-Benz, or are you going to settle for a Ford?
Looking forward, I've been putting some effort into getting to grips with iOS application programming. I'm looking for some ideas for simple apps, like reference and calculations perhaps. Anyone have a need for an app that they'd like, but isn't available? Or perhaps an existing app that doesn't quite do what you need? I'd be interested to hear, and may be able to help.
