The way to get USD 100 PCs is to recycle them. As the users in the worlds developing markets buy new computers, their old computers need to find their way to the worlds emerging markets. Everything in a PC is built to last. Computers, in fact, have a lifetime much beyond the 3-4 years that weve been using them for. Look at cars. They are used, and used, and used for 10 years or more. The users may change, some parts of the car may change, but they are not junked to the Recycle Bin after a few years.
The problem with using older computers lies not in the hardware, but in the software. The older software is removed from service every few years, leaving little choice but to upgrade because the newer versions require more firepower memory, processing power and storage. Think about it for a moment. To use a 3-year-old PC, you will need 4-year-old software to ensure adequate performance. But can you buy older versions in the market? We cannot get Microsofts Windows 95 or 98, of Office 97. In fact, come next April, and the only Windows version available will be XP. No prizes for guessing the kind of hardware one needs to run that.
What compounds the situation is the cost of the software. Microsoft needs to be paid more than USD 500 for its combination of Windows and Office. Thus, the base cost of the computer for hardware and software exceeds USD 1,000 (Rs 50,000).
This is the game which the Intel-Microsoft nexus has perfected in the past 15 years. This is the nexus which needs to be broken if the worlds emerging markets want computers to penetrate as deeply as they have elsewhere.
The solution to the software lies in using old PCs as Thin Clients in office, and at home. What this entails is a shift to server-based computing the use of Thick Servers. What can make this possible now is the bandwidth revolution of the past few years.
The distance between the Thin Client and the Thick Server can be measured in hundreds of metres, unlike the few centimeters of the past. In other words, one had to use Thick Desktops because the LAN/WAN speeds were not great enough to be able to support a large number of Thin Clients users concurrently. With 100 Mbps LANs and the coming Gigabit Ethernets, this is no longer a concern in the enterprise. From the home users point of view, cable modems can provide a reasonable bandwidth to the home, as do wireless LANs. Both of these enable the server to be located remotely.
By using Linux and applications like KDE (desktop), Evolution (email and calendaring), Mozilla (web browser) and OpenOffice (word processor, spreadsheet and presentation), it is now possible to eliminate the need for proprietary and expensive applications on the desktop. For example, the most recent release of OpenOffice have made it good enough to open most of Microsofts Word, Excel and Powerpoint files, making it possible to notrequire the use of Microsoft Office for reading and writing documents in the de facto standards. This is the corner turn for creating a viable alternative to the Microsoft monopoly on the desktop.
Thus, recycling older computers and converting them into Linux Thin Clients can bring down the cost of the desktop to USD 100 or less. This is the 10X tsunami the cost of computing brought down by a factor of 10 will make the computer affordable to a whole segment of users who previously could never been imagine using one. This is at the heart of the revolution which needs to cut across the worlds emerging markets.
