I agree on that, but I'd still have to have an extra pc with awesome miner running 24/7. That's why I'd prefer to get the mail directly from the pool.
Haha! By the time you get the email directly from slushee, you have lost your reward if they hit a block while you miners are down. The iPhone and Android app along with the Zachmonroe web site gives the same notifications here but you don't lose any rewards with 5Nd here.

With both the App and the Zach email notifications, it tells you exactly which machine has dropped below the hashrate level you determine.
Example:
