Awesome guide!

Hi Joey - I think you might have missed the point. iFixit's Teardowns are 'first glimpse' looks inside a device, created the day that a device is released. They are meant to be a summary overview of the highlights of a device - infused with some humor.

If you're looking for a complete set of free, thorough, and detailed disassembly and maintenance guides, just look at the 23 guides on iPhone 5 Device Page: iPhone 5. Hope this helps!

You're completely correct - all jobs are somewhere between difficult to impossible to do if you don't have the right tools. The big difference comes when a manufacturer starts inventing new proprietary tools - that most definitely makes a repair harder. We don't want you to have to buy proprietary tools (from us at iFixit, or from anywhere else) in order to do your repairs. (So that you know: iFixit only has Pentalobe screwdrivers available because we reverse engineered the screw, and started manufacturing our own screwdrivers.)

For your consideration - what if the phone had Phillips screws instead? Almost everyone owns a Phillips screwdriver already. Even if you don't, chances are very high that your neighbor or friend has one you could borrow. When a manufacturer invents a new, proprietary screw bit, then doesn't make the matching tool available, it makes repairs unnecessarily difficult (and expensive!), and that's something iFixit has taken a stand against.

You can use a different type of thermal paste, but we recommend Arctic Silver.

Yes, this seems likely to us at iFixit as well.

iFixit sells the battery you need for $119 (http://www.ifixit.com/MacBook-Parts/MacB...), and once you get it, doing the replacement shouldn't take more than 30 minutes, even if you've never done a repair like this before.

Some people will build their own machines, and install SteamOS on them. Valve encourages people to do just that. I think this option is more targeted at people who don't know how to build their own computer, or who simply don't want to build their own.

The photos aren't failing to show up, there just aren't any photos - no one ever uploaded any, even though the text of the guide talks about the pictures. As you're doing the upgrade yourself though, snap some pictures, edit the steps here, and upload your pictures!

I made the change from three to four screws, but you're able to edit the guides as well. If you want to edit something, you can click the Edit link on the right side of any guide step, or the Edit link at the top right of the page (sandwiched in-between View and History).

You can get the two thermal sensors, listed as the Saeco Brew Thermostat 95c, and the Saeco Steam Thermostat 127C, from Stefano's Espresso Care, http://www.espressocare.com/. At the site go to Parts>Home Line/Prosumer>Saeco, then scroll down page 2 and you will find the parts listed.
