Apple needs to do tv, cars, and home automation.
I know Apple has their Apple tv but they need to move from hobby stage to full blown cable replacement. They need live tv for sports and news and they need to offer shows a la cart. I could see 99 cent per hour show or something like that. Maybe let us choose whether we want commercials or not. That could lower the price quite a bit.
Cars are a no brainer. Cars need to make slots for iPads and iPhones. You just insert your device and run the app for the vehicle. You take the app when you get out of the car. Car companies can then just create the i/o and the software and let Apple do the computer side of things.
For home automation, I had always been a skeptic until I was trying to make my new cabin more energy efficient. In sizing generators, solar panels, and all the appliances, it hit me how important having smart appliances really would be. It is really important that appliances talk with each other, know typical daily usage, typical temperature changes, etc and schedule which appliances get the electricity when. If the appliances, hot water heater, air conditioning, generator, etc all talked, they could cut our electricity needs quite a bit.
By smart appliances I do not mean $300 extra per device. It should be more like $50 per device. But this would save lot more money in the long run. This is the killer app for smart appliances, not knowing when to order milk in the frig.
I don't want is my frig compressor turning on when my hot water heater is working as my dryer is working as my toaster is working as my microwave is working as my AC kicks on as I turn on a light. One needs a huge generator to handle that load. However, if all the devices talk to each other, they could schedule when they kick on and off and balance the load. This would not only help a local generator but also the whole electric grid. They would have a lot less peak needs and a steadier demand which could lower their supply.
In addition to these three areas, I would love to see Apple get into security type systems - home, car, other significant gear. Steal my car and I know where it is at. Break into my home and I get instant notification and video. Find my iPhone is already in that direction.
Also, I would love to see Apple do more software - Photoshop, Illustrator, Dreamweaver alternates. I love Pixelmator. Don't tell me Apple could not buy them out and make it a full-featured replacement. Free me from Adobe and don't let them hold Apple hostage.
And bring back iWeb but make it a consumer level app and a pro level app. Easy forums, web store, mercy account tie-ins for the pro level app.
I would also like to see Apple release an accounting program for businesses and make the source code available to programmers for customization. Do this accounting app for low cost and they would have businesses leaving Microsoft in droves.
Apple also needs to move their OS to a full metadata based system and bring back OpenDoc. They already have most of the pieces to do this. In fact, it would surprise me if they aren't doing this already piece by piece. It didn't work in the past but we have enough processors, RAM, and core libraries to do it now.
I also would like to see Apple get into DMW lighting, video switchers, and audio mixers. Final Cut X has the code to do the video work, Logic X has the code to do audio work, and DMX is even easier. I would love to see Apple embrace the professional production world and step on the rest of Avid's toes.
Apple needs to expand iTunes U into a full blown education place that replaces most brick-and-mortar schooling. They made the music stores and video rental places extinct, why not traditional schools? The sooner we get government out of this area and let the market place/parents run things the better.
Apple has lots of room to grow, but only if they are willing to embrace these areas. Some are consumer areas and some are pro areas. Some are hardware, some are software. But all touch on areas Apple is already involved in. Apple needs to embrace their destiny and do what needs to be done. If they don't, they form a barrier to others who see the potential is all these areas.
