Apple vs Google. "Closed" vs "Open".

Image by marcopako  via Flickr

I hate when some people give name calling to companies like Apple. Below is my respond to one of the Forum post in Low Yat Net.
This is also a continuation of my article posted regarding "Are you an Android or iOS Fan?"

------------------------------------------------------

Both Apple and Google have to different business strategy.
You cannot simply start calling names Apple as "n00bs" market segment or "kiddie toys" when you don't know how much Apple is worth as a Company nowadays.

Google makes money out of its advertising business. Thus, data, information and knowledge is very important for them. Google is not in the business of hardware like Apple. That's why they gave out Android almost for free (or totally free probably) to handset makers. Google is very clever in trying to make all smartphones to have Android. When people use their device, they will capture the user profile. Smartphones are more personal than normal desktops. Thus, usage of smartphones can be leverage by Google for Advertisements. Users are being profiled this way.

Now Google is moving another step further into the realm of "Internet of Things" or IoT. Why Google is interested in this? My personal opinion is that they would like to capture the profile of "Things" such as Fridge, Cars, Electrical appliances etc. These "things" will have sensors that sends out data. And this data is what Google is interested. In future, Google will exactly know what devices or "things" in your house and what are your buying preferences (brands, types etc).

But Apple Inc, is not trying to capture this market. They have tried to open their Macintosh OS to other hardware players previously but it failed. To understand why Apple have a "closed" system is to understand Apple history and how Steve Jobs built the Company. This is a long story and I suggest read the latest "Steve Jobs" book. But to make it short, Steve wanted to make his product a perfect product and closed. That's why people even have difficulty to open up Apple products without a proper tool (Apple even design a special screwdriver to open up their product). They don't even allow user to change the iPhone battery so easily! (Take a look at Samsung phone - see how many people in the Forum is trying to buy spare batteries!!).

Steve Jobs is meticulous in designing Apple products. Before Steve joined back Apple, the company has so many products that they need a Chart to show the product line. Steve terminated so many and finally chose a few to continue. Apple iOS is closed and they never allow users to mod it. But the hackers are always 1-step ahead of Apple. This cat-and-mouse game of Jailbreaking will always continue but that's what excite some of the users.

But why Apple chose a "closed" system as their business strategy? Apple not only in the software business but also in hardware business (unlike Google). Thus, selling hardware is also their main business and the only way is to ensure they control the Quality of their products is to have a "closed" system. Apple has Millions of users even before they launched iPhones. iPods and iTunes are the beginning of their Apple eco-system - now they have entered the music industry with iTunes and iPods/iPod Touch, TV industry with their Apple TV, phone industry with their iPhones, Games and Media industry with their iPads, Computing industry with their Macs and Cloud business with their iCloud.
As for the "closed eco-system" users, they will benefit from high quality and seamless usage experience (if you were to choose all products from Apple). What's more important for these kind of users are productivity and change the world with Apple products. Unlike most Android users who always "kill their time" with "modding" their gadgets but not doing so much about productivity (my personal opinion when reading the Forum posts).

Thus - Apple is not a eyeing a "n00b" market segment and neither its iPhone is a "kiddie" toy.
Learn more about both Companies and you will respect both of them. Its either you are in the "open" market segment or "closed" market" segment.

Its either you love it or hate it.

App Store Strategy - Closed Wall Garden Approach

A couple of years back, many telcos tried the "Wall Garden" approach whereby the telcos have their own branded "portal" or "website" that gave their subscribers the ability to access and download contents such as music, ringtones, wallpapers etc. i-Mode is a typical success story. However, it seems this approach cannot be successfully duplicated in other countries. Why?

1. The phones (unlike today's smartphones) are not ready to download contents like music and applications. They are "meant" to download simple contents such as ringtones and wallpapers which are easy to be duplicated elsewhere. The subscribers can easily cut .mp3 files to be ringtones and also create their own wallpapers using free Utilities.
2. Most portals are being created by major phone manufacturers themselves like Nokia. There are attempts by various music portals to be offered as part of the telcos wall garden portals. These various content providers makes the handling of telco portal a nightmare. The telcos are not in a good positioned to become a content aggregator.

So, how different is today's Mobile Portal? Apple has introduced iTunes Store for many years (since 2003 and later launch App Store in 2008) and their first customers are on fixed Internet. Initially focused on entertainment contents, they have now moved to application contents. When Apple introduced the iPhone in 2007, the whole mobile Internet landscape have immediately changed. Why?

1. Apple have Millions of loyal customers before they launch their 1st smartphone i.e. iPhone and the App Store. They are PC, Mac, iPod and iPod Touch users. All of them require iTunes to sync the music, video and the apps.
2. Even though they have iPhone users, there are still a big percentage of the customer base are using iPod Touch to access the Net. Most of the iPod Touch users are young ones who cannot afford to pay high mobile data charges.
3. Once the young users become a working adult, they are now able to buy a higher end device such as smartphone and also afford to pay for the mobile data charges.
4. Most of the Apps found in the App Store requires a connectivity to Internet.
5. The commercial app is cheap - begins from USD 0.99. Thus, number of downloads is significantly high.
6. Apple Store provides a consistent purchasing experience and maintain a single portal. Thus, a user felt safe to make a purchase knowing the license are well maintained at a centralized server maintained by Apple. In addition, the user themselves can change device or computer and yet don't have to make another purchase.
