Hi Michael,

According to RFC4918 (June 2007) Adding a calendar resource could cause
a lost-update so clients are advised to use on of the following scheme:
1) If lock is supported request a lock on and Unmapped URL
2) If lock is not supported use the header If-None-Match (RFC2616)

As I see it using If-None-Match header is more flexible and requires
less from both client and server. My question is then: Are there any
added benefit from using a Lock on and Unmapped URL if the server
supports locking or should I use If-None-Match header anyway?

If-None-Match is probably best right now. I think LOCK is more useful when you need to make multiple updates and ensure those are consistent.
