Issues like he could not mount DMG's, so they helped him find the corrupted file, and get rid of it. Also, there are a few trojans for mac, but no "viruses".

Those issues aren't virus-related. And yes, there are a few trojans, as the link I posted states.
 
The advice about backing up and getting a lock is excellent.

Also, one of the best ways to keep your computer running speedily is to erase and reinstall the OS every 2 years or so. (And I mean actually reinstalling everything, not restoring from a Time Machine backup). Even though OS X slows down less than Windows, over time you can get enough crap building up in your Library folder, as well as corrupted preference files and the like, that reinstalling makes a big difference.) Before i used to do regular backups this was a huge pain but now with Time Machine it's actually relatively painless.
 
I don't think the vents in the back recirculate the hot air out and back in, that'd be poor design..

thats the design,

there is no possible way air gets in through the keyboard, its sealed with plastic.

air is brought in and out from the back, the design works well, unless your a engineer then i guess calling it a poor design is meaningless.
 
I did not say that they were virus related. I just said that he had a few software issues and they resolved them for him.
Your previous post indirectly inferred that the Apple Genius helped remove a virus:
If you get a virus, they will (probably) help you remove it. When my brother had issues on his computer (software) the apple genius helped him fix it..
Now it's clear that those two statements are unrelated.
 
How to make it last 4 years? If you want it to be in pristine condition then the invisible shield, keyboard cover, and palm cover is probably a good way to go.

But really, all you need is Apple care and use a case. Also, take good care of it. That will last you 4 years for sure. You don't really need the accessories unless you want it to stay in pristine condition.
 
just another note:

i just remembered the taking your laptop on the field trips are for the over night field trips, which there will be alot of... (we go on two field trips a month)
 
the vents are in the back... i should know... my mom has a MBP 15" and some of my friends have MBP 13" and then heat up in the back, where the vent is.

You are only looking at the exhaust vents. Where do you think the 13 gets the intake from? I am not saying that a keyboard cover will cause your MBP to over heat but I am just explaining how problems may arise. If you ever take the MBP apart you will see that the actual fan has an opening right under the keyboard that takes air in, and pushes the hot air out of the back vents. This link is for a 15 MBP but the idea is similar. http://www.ifixit.com/Teardown/MacBook-Pro-15-Inch-Unibody-Teardown/590/2

This is how it looks like it works to me. The airflow is split between the top and bottom of the logic board.

Red is hot air
blue is cold air.

But won't Time Machine just put all the unneeded library and preference files back on your new install? I notice that all the library files are in my Time Machine backups.
 
My MBP hits it's 4 year mark this year, and I've barely put any extra money into it, with the exception of doing my own RAM and hard drive upgrades. Do things like letting your battery die every now and then, that will help extend it's life. Keep it clean and don't block the vents.

It sounds cheesy, but just treat it with respect. I've been running heavy software on mine, and treating it rather rough, and it's been good to me. I use no covers, or special fans. I have had no problems with it, and I am anticipating many happy years in the future, before I am forced to upgrade.

*knock on wood*

Quoted for truth. My MBP is on its third year and the only upgrades I've done personally are the hard drive (difficult) and the RAM (easy). It's also had a logic board replacement and a DVD drive replacement (neither my fault, covered under Applecare or just plain fixed for free). The only things I'm still considering are a new battery (user replaceable FTW) and maybe a new charger if the cord on mine frays.

I don't think this is necessary. Just periodically go through your library folder and delete any unnecessary folders (ex. CS3 files if you've upgraded to Adobe CS4). Reinstalling the OS is like using a sledgehammer on a drywall nail.
 
Just use it and don't worry about it too much. Take precautions not to bang or slam the machine, particularly when it is running. Also, make sure drinks are placed far away. Other than that, with normal use, it should easily last 4 years.
