MacBook Air and OS X Lion synergy: A big hurdle for Windows 8

Unless you have been sleeping in a cave somewhere, you know that Apple released new MacBook Air notebooks and OS X Lion together. The joint release is significant because Lion is designed from the ground up to optimize the user experience on Apple hardware. The synergy between these Apple products is powerful stuff, and demonstrates the big task ahead for Microsoft’s work in progress, Windows 8.

OS X Lion has a raft of features designed to make working with a MacBook Air, even older MacBooks, as intuitive as possible. The ability to have lots of programs running and easily get to any one of them is already changing the way I work with OS X. The handling of the small notebook screen is pure genius, as is moving between programs occupying the entire display via simple touch gestures. The hardware and software have been written from the ground up to work together.

Apple hasn’t done this overnight, it has been laying the groundwork for this synergy for a while. It started by putting large touchpads on every MacBook, and carried it over to non-notebooks with the release of the Magic Mouse and Magic TrackPad. The groundwork for a touch optimized experience was laid even before the iPad hit the scene. The company had a good plan and has executed it well.

This is the giant hurdle Microsoft faces with the next version of Windows, not so cleverly codenamed Windows 8. The sneak peeks Microsoft has given us of Windows 8 show an exciting new direction for the platform. Windows 8 attempts to do what Apple has executed, making the OS work efficiently with the system in the user’s favor. What will determine how well consumers react to Windows 8 when released will be how easy it is to use, especially on notebooks. Windows 8 must find a way to handle smaller displays intelligently like OS X Lion, and bring touch (not necessarily the screen) into the equation.

This is a daunting task for Microsoft as a software company. The legacy of Windows is that by design of Microsoft’s business plan, it must work on a wide variety of hardware made by other companies; this is not a complication faced by Apple. Microsoft decided long ago to be a software company, and this is now a competitive disadvantage. If it has to compromise the user experience offered by Windows 8 to make it work on some hardware, it will not compare well with OS X. That is a simple fact of life in this competitive environment.

Computer users have evolved the last few years to expect systems to be easy, even enjoyable to use. In the early days of Windows we all expected things to be complicated, and keeping everything going properly required access to an “expert”. Those days are gone, folks now expect their computer to just work, and be intuitive at that. This is the biggest obstacle facing adoption of Windows 8, as it means the OS must work on whatever hardware Microsoft certifies it for, and run well.

I am optimistic about the next version of Windows, more so than with any version in a long time. I hope that Microsoft’s decision to broaden the scope of hardware that Windows 8 will service doesn’t turn into a bad decision. Apple’s ecosystem is getting better due to the limited hardware focus needed due to building everything internally. Windows 8 doesn’t have that luxury, and that may be an awfully big a hurdle to jump.

Big files, Fast Internet? Lion download speeds

By Steven J. Vaughan-Nichols | July 20, 2011, 3:17pm PDT

Summary

No one with a slow Internet connection is going to relish downloading Mac OS X Lion’s 4GBs, but if you have the pipes, the downloads seem to be working quite well.

My buddy Jason Perlow had a bad day. When he tried to download Mac OS X Lion’s 4GBs, he ran into an hour-and-a-half of online road-block. When the download finally did start though, he was able to download it, thanks to his 100Mbps Verizon Optimum Online Ultra connection in about half-an-hour.

So, which can you expect? An hour and a half of freeze or a relatively fast download? I say “relatively” fast because in a perfect world 4GBs on a 100Mbps connection should take about five minutes. To find out what other people were seeing, I did an informal, totally unscientific survey of my high-tech friends on Google+ and Twitter to see what their experiences were like.

And, the answer, if you’re lucky enough to have a real broadband connection, is: Fast.

One friend reported that “I must have gotten lucky. My download took less than 30 minutes on FiOS. Install, likewise, was half an hour. The entire process was far less painful than anything I’d experienced before. And that, frankly, is surprising…because I was expecting more snafus since Lion’s been positioned as a major upgrade.” FiOS, a fibre optic Internet service offer from Verizon speed ranges from 15Mbps to 150Mbps. He was running at 50Mbps.

Others, running everything from AT&T Uverse a DSL Internet service at 12Mbps tocable service users in the 15 to 100Mbps range saw download times ranging from 40 minutes to the guy with the 100Mbps connection who downloaded it in five minutes.

Me? I did it in 12-minutes with my newly configured Charter Ultra60 connection.

So, what does this mean?

Well, it seems to me that Akamai, the content delivery network (CDN) behind the Mac OS X Lion roll out, is doing a good job.

Akamai did its CDN magic by hosting Lion on over a thousand servers in multiple Internet backbone and end-user ISPs. In the case of Lion, Akamai preloaded mirrored copies of Lion. Thus when you bought Lion, your data request was sent to “closest,” in terms of distance, network load, and latency, Akamai server.

So why did Jason run into trouble? He thinks it was because Akamai’s distributed, front-end IP load-balanced methodology ran out of slots. I strongly suspect though that the blame goes to Apple’s datacenters.

In the Akamai model, no stream can start until its servers have been given the OK from the authorizing site. In this case, that would have been Apple and that sounds to me like exactly what happened.

All that said, this only really matters if you’re like me and my friends who have a fast broadband connection in the first place. Many of you, most of you, don’t.

According to Akamai’s State of the Internet report for the last reported quarter of 2010 in the United States only 34% of users have “high broadband connectivity.” That includes 27% of connections between 5 Mbps to 10 Mbps and only 7% reaching above 10 Mbps. That’s lousy.

Even at a 10Mbps connection, if all goes well, you’re looking at just under an hour to download Lion.

Now, I’m a big believer in cloud computing and devices that rely on them, like the Chromebook, but then I have the bandwidth to use them. I think Apple was premature in releasing Lion as a download only upgrade. For all too many users in 2011, a DVD would have been the better option for Lion. Going online for it should have been left as an option for those who are lucky enough to have serious broadband in our homes and offices.
