    So, having installed Lion + updates + XCode, I am using a total of 76GB. The size of my home folder is 56GB. This means that the applications and system files amount to a total of 20GB. This seems like a lot......

    How much RAM do you have? There is a sleepimage file of that size used when the computer hibernates. It's in /var/vm. For example, my 8 GB MBP uses 8 GB of disk space for that file.

    Ha! Indeed, there is a 4GB (I have 4GB ram) file in that location. I am guessing this is to save the ram to disk when the computer goes to sleep? Is this file permanently present?

    So, that takes the install down to 16GB... still seems like a lot.

    if you want to get that 4GB back you can do this.

    I have done this and it works great, I got back 4GB and I also get quicker shutdowns and being that in Lion all app windows reopen to there last saved view I see no reason to write the RAM data to the hard drive

    20GB doesn't seem like a whole lot.

    ~8.5GB - Lion (install size)
    4.0GB - Sleep Image
    ~5.0GB - Xcode (install size)
    ~2.5GB - Other Apps and system settings (e.g. Spotlight index files, etc..)

    I disabled hibernate and removed my sleepimage first thing after getting a SSD.
