I know MobileMe does more, but a competing product as far as location and ability to wipe and backup remotely has had their registration page broke for days now.
www.cylay.com Try to register. You can only type one character in the password field! These guys only charge $19.95 a year. With this problem, they won't get any new customers! Duh. Is it just me or are others seeing the same thing? It's like someone broke the page on purpose or something as it is such an obivious problem.
I can see them wondering why they aren't getting any signups. Send them an e-mail.
