This is a great point. Also, even if it is actually cheaper in the long term because they can just upgrade parts from the modularity of it, I somehow feel skeptical that a school IT unit is going to have that level of foresight. Even if they do, will they be able to successfully persuade the suits that control the budget?

Yup, you're right, this could be a very tough sell.

It would need to last 3 times longer before needing a single replacement part for the cost to lifetime ratio to even out. Each replacement part in that timeframe pushes the value time out further. I'm not convinced it would be cheaper in the long run.

You think those IT people don't read here too? Its a budget thing sweetie, once you get a real job you understand.

I wonder how often they have to replace those low priced chrome books, however. Maybe there is a good value proposition in buying a well powered machine that can be updated by an IT department in an age where laptops are never upgradable.
