TCO

Another OLPC TCO study

1:1 Computing costs are a difficult thing to nail down, because there are so many factors that go into it. I worked with GeSCI's Roxanna Bassi to create a worksheet to help guide cost calculations. I took a first stab four years ago, and came out with a $972/laptop cost over a 5 year program. To say that that cost estimate was not popular at the time would be an understatement.

OLE Nepal has put together a great TCO of the laptop program, based on their pilot project. Where I pieced together training budgets from USAID ICT4Edu projects and Internet connectivity estimates from UN/ITU global averages, they have on-the-ground numbers, (and a few ideal estimates on repair costs). The total for a 5 year program in Nepal? We're still looking at $753, if you read carefully:

OLPC TCO Deathmatch (2 of 4)

Let's talk Total Costs of Ownership of One Laptop Per Child. Taking our set of different OLPC implementation cost calculators, as well as actual numbers that have bubbled up over the years, like IADB's Project HA-T1093 with 13,200 students plus 500 teachers (with a budget of USD $5.1M), we can try to settle on some generalities so we can compare apples to apples.

Common Basic Assumptions

Let's start with how long the project will run, and what number of laptops we'll need to replace (due to age, damage, loss, hardware failure, and so on) during that time frame. That should be easy, right?

Five seems to be the magic number when talking TCOs, which is convenient when projected OLPC lifespans are also five years. Reality may disagree with that (and certainly GeSCI and Vital Wave wisely do).

So let's plan for five years, and drop re-purchasing of the whole batch within that period (see below for why this becomes relevant). We'll instead presume some per-year replacements (damage, theft, environmental problems, and "normal" wear-and-tear), but even this gets harrowing.

Different Lifespan Calculations

The OLPC Deployment Guide handily provides numbers for expected monthly repair frequencies, which they project at .083% risk of bricking per laptop per month - 1% failure over the course of a year.

It's Raining OLPC TCOs (1 of 4)

Update: Hello readers from Alanna's post on the OLPC at UNDispatch - You should check my original article on the OLPC TCO - written back in 2006 - over at OLPCNews.com.

If you poke around enough on the Laptop.org wiki, you find a few interesting corners. Linked from their work in creating a training and reference document for OLPCCorps, a link to an Excel spreadsheet to calculate OLPC-specific costs for a deployment, which has been created and maintained by OLPC's John Watlington

Microsoft, the "third world" and anti-virus

For the past year or so, I've repeatedly been trying to bring up what I see as a huge, gaping hole in any project which uses Microsoft products for an ICT4Development rollout - computer viruses. Windows XP, when connected to the Internet sans protection, lasts as few as four minutes before becoming infected, and rarely more than a day. Multiply that by hundreds of thousands of OLPC XOs running Windows (with no mention of anti-virus software to date), and you have a nightmare scenario pretty rapidly.

The much-debated VitalWave TCO paper we discussed at the World Bank, which argued that the higher cost of Linux administrators balanced out licensing costs for discounted Microsoft and anti-virus software, even admitted the significant costs of purchasing and maintaining a subscription to anti-virus tools

If Microsoft wants to continue to capture the developing world market, this is going to be a barrier. They can drop their own licensing costs for the XP Starter Edition (which at this point is zero cost to them) down, and hand out older Office software; but the initial and subscription costs for anti-virus software are not (directly) under MS's control. Regardless, having anti-virus protection directly impacts the functionality of the device - if installed, A-V can slow a less powerful computer down to a crawl during a scan and at startup, but the consequences of not having it can render the system absolutely useless.

So it comes as little surprise that Microsoft has announced a free anti-virus software for XP and Vista that targets lower-powered systems (cough, like the OLPC?) to address both these problems and lower the cost barrier for adopting MS:
