There's a reason why security-conscious folks spend an enormous amount of money on the stuff that we buy for a couple hundred bucks. I'm sure that the NSA pays thousands for $100 hard drives.
Heart of the matter is that most consumers - whether personal or business users will have little to no visibility into this. And, even a smaller fraction will have the technical chops to remove this garbage unless there's a tool that's openly presented to them.
Since there are a ton of small businesses that purchase and consume laptops just as the come out of the box, I'm really interested in the industrial espionage potential with this.
Couple in all the PRISMish like revelations over the last year and a half, and I simply have trouble putting much faith in their, "oh, it's just to show better ads, sorry..." statement.
There's certainly an unrealized support cost. But in my experience, it's pretty common to see several different manufacturers and OSs across a small business. When they need a new laptop, they're either picking up what's cheap at Best Buy or handing down machines when the boss gets a new one.
