Apple's (NASDAQ:AAPL) MacBook Air is due for an upgrade during 2014, particularly as the Windows notebook/Ultrabook ecosystem has aggressively pursued high-resolution displays, slim displays, and even touchscreens. While Apple aggressively pursued improved battery life in the 2013 MacBook Air -- and arguably did a better job utilizing Intel's (NASDAQ:INTC) Haswell than any other PC vendor -- the next-generation MacBook Air is going to need a major new selling point. Just what could it be?

Bye-bye fans!
At the Intel Developer Forum, Intel talked about how its next-generation Broadwell processor would enable fanless Ultrabook/convertible designs:

Moving to fanless systems offers some pretty tangible benefits. According to Intel, fanless systems offer the following advantages over actively cooled systems:

  • Silent
  • Industrial design freedom -- which means thinner designs, designs without vents, and sealed designs
  • No moving parts, so the systems will be more reliable
  • More battery capacity, since the active cooling system took up space that could be allocated to the battery

Apple is well-known for gorgeous industrial designs that maximize the user experience. Apple also likely heavily influences the design of Intel's chips. So, it seems only natural that a next-generation MacBook Air would take full advantage of the benefits of a chip suitable for fanless designs.

What about that iPad Pro?
What's interesting is that Apple is reportedly planning a larger iPad, commonly referred to as the "iPad Pro." This is supposed to be a convertible, productivity-oriented device built around Apple's next-generation A8 chip and iOS. This seems a lot like a MacBook Air replacement. However, since it doesn't run full OS X, there will still be users who want a full productivity-oriented product.

Further, a product built on a low-power Intel Core processor is likely to offer some pretty significant performance advantages over a next-generation Apple A8 system-on-chip, even in a fanless form factor. Indeed, today's Haswell-based MacBook Air offers well more than twice the CPU performance -- and multiple times the GPU performance -- of an Apple A7 running at full-tilt. It would be difficult for Apple to outright replace an Intel-powered device with a custom device without taking a potentially noticeable performance hit. The MacBook Air and iPad Pro will likely co-exist, with the former powered by Intel and the latter by Apple's own chip design.

The lines are blurring
The bottom line is that the lines between a large, high-end tablet and a traditional PC are blurring, and it's already clear that the MacBook Air and iPad Air lines are converging. While Apple's mobile chips are quite formidable, they are still fighting the MacOS software base, Intel's much greater experience at high-performance processor design, and a manufacturing disadvantage on the part of Apple's foundry partners. Apple will still likely continue to push forward its MacBook line, even if the iPad line begins to start acting more as a substitute for these products, rather than a complementary one. 

The next big trend in tech is here, and you can profit
If you thought the iPod, the iPhone, and the iPad were amazing, just wait until you see this. One hundred of Apple's top engineers are busy building one in a secret lab. And an ABI Research report predicts 485 million of them could be sold over the next decade. But you can invest in it right now... for just a fraction of the price of AAPL stock.
