iMac construction

I would consider buying an iMac since it's performance has now exceeded the Mac Pro in it's current guise. But, I can't imagine having the hard drive fail (and it will) and needing surgical skills to remove it. Why would Apple design this thing worse than a cheap netbook or laptop, where you need to remove a single screw and slide it out.

I'm just ranting because I want a new computer and I'm tired of waiting for Apple to release an update to the Mac Pro line.
