Definitely, as they're behind any other vendor in this regard.
As per more than that, going by history, Apple's not interested in offering more than that really. They skip out on features that you'd find on other boards, such as SAS, built-in RAID,... Apple even cheapens out on warranty support, as 3yrs is standard on other enterprise systems from any other vendor. Some may see this as nitpicking, but I don't. It's a big deal to IT and business personnel, as it means more $ has to be added to get close. Unfortunately, it really isn't, as Apple expects users to take it into a store, not provide it as On-site, which is standard anywhere else. Granted, On-site support is available under certain conditions, but they make users feel like a massive favor is being granted in those cases. Not so with anyone else (in terms of vendors), as it's standard. No expectation of the user to lug the system into a repair shop in order to obtain warranty support.
