GamersNexus wrote a piece that claimed Mirror's Edge: Catalyst has DRM that limits the number of hardware changes to four. According to an email from EA's press contact, it turns out that GamersNexus' article is not accurate. According to EA PR, if Origin detects five activations in a single day, the user will need to wait until 24 hours after their first activation to attempt again.

So you can change your hardware as many times as you want over the life of the game, just not more than four times in a single day, on a single account at least.

This message didn't seem to say what they were implying it did. Turns out, it doesn't.

I decided to ask EA when I read the error message that GamersNexus posted — the article's  interpretation didn't seem right. The wording was as follows: “Too many computers have accessed this account's version of Mirror's Edge(TM) Catalyst recently. Please try again later.” It seemed very odd to me that the wording “recently” and “Please try again later” would be attached to a permanent bricking of the game.

Again, it turns out that this is not the case, unless our press contact was not up to date about this specific title. As much as I dislike DRM, being a proponent of art preservation and archival, this part of Mirror's Edge's DRM should not affect the vast majority of users. This is something that should only affect people who are literally benchmarking a half-dozen (or so) graphics cards.

In short, it sounds like this is a non-issue after all.
