    Will you be doing a clean install of Lion, or simply upgrading over Snow Leopard? Feel free to elaborate on why you made your choice.

    Upgrade. I don't see the need for clean install. Unless there's problems, it seems like a waste of time.

    This. To be honest, I don't really have enough time to do a clean install and then transfer all my files back over.

    I just erased my HD and reinstalled SL on my MBP in atancipation for Lion. So far, my MBP turns on noticeable faster and all is stock. This is my first time reinstalling since SL came out and definitely worth it.

    Clean install. I've needed to reformat/reinstall SL for a while (for organization issues, not speed), so I'm waiting for Lion to continue.

    Clean install is a myth. The install is clean just for a very short moment until you begin to restore your data including your library.

    I am pretty sure that an upgrade to Lion will remove almost all mess you can imagine in your system folder. The problem is the user's library folder.

    And if you begin to re-install SW like Elgatos eyteTV or other SW, which comes with System extensions, unclean, unclean, unclean ....

    If you compare total disc space after an upgrade and after a "clean install" you will see some difference, of course. Typical examples are fonts, which came with non-Apple SW and are lost after a "clean install". But the few kBytes you can save cannot justify the pain when you open a document 5 month later and you learn that some fonts are lost due to a "clean install".

    Stay dirty !! Its much more fun. :D

    I on the other hand always make a clean install and transfer the stuff I want to keep manually.

    Now I could try to justify it by pointing out a bunch of .0-bugs people encounter that are related to an upgraded system (mostly because of third-party hacks though), or that the system might have been tested more on fresh installs.

    In reality, it is more of a fresh start, a way for me to organize my files and setup a bit. With OS X continuing to "just work", day out, day in, stuff gets left behind and forgotten.

    I will do a clean install because I haven't "cleaned house" on my HDD in about a year or so. I also like that fresh feeling of putting in new settings and customizing apps again. ;)

    This is why I do it too. I do see a minimal performance boost when I do a clean install, but the boost alone is not worthy enough of a clean install. I do it for the reorganization purposes. Makes me feel...cleaner!

    Interesting results. I'm personally straddling the fence (which is partly why I created the poll). I like the idea of setting things up new and fresh, but at the same time it seems like a huge hassle to migrate all my data back over again. I will likely just upgrade this time since my MBP is only a few months old anyway.

    Nothing wrong with this attitude.

    But I always prefer to go clean from scratch before throwing all my apps on top of it - one by one. Makes it easier to narrow down exactly what to blame should a problem arise.

    It's just too easy to upgrade on top of SL and blame Apple for Lion problems when it might very well be some other 3rd party crap responsible and indeed it often is.

    That's my experience anyway. And besides, I'll make the time for it.

    Clean install for me. I don't have a lot on my mbp anyways. Most of my important docs and media are all in my external HD

    I've been mulling over the clean install.
    Can anyone tell me, how does it work? Do you backup, install Lion fresh and then manually drag in your User folder and install and SW? Seems like a hastle, but maybe I'm not thinking right.

    No difference

    The whole system gets changed. All system files are updated - i.e. are overwritten by the installer. So in reality there's no difference in a clean-install or an upgrade.

    But a clean install just gives a psychological effect to freaks like me. I bet most of the UNIX experts will go for a clean install. Freaks as I said.

    But an advice for all those who don't bother what's installed on the system - make sure its an upgrade otherwise its just a waste of time.

    I'll be doing a clean install since I just bought a larger HDD for my MBP. Time for some much needed cleaning of all my old files.

    Clean install when the 10.7.4 will be released. I tried the GM... too many bugs,
    i stay with SL.

    Clean install. Always. I'd rather not half-ass things or take the lazy way out when it comes to OS installs.

    Already did a clean install to the GM. If anything is different or they seed another GM to devs, then I'll just upgrade from there (if possible....)

    Upgrade is still an upgrade

    These questions are a little blurred.

    Upgrade or clean install?

    Whether or not you clean up the system first, isn't it just going to be an upgrade over SL either way? You'll just be putting all the files you stored back on it anyway. It's not like you can just pop in a disk and do a full fresh install from the "full" version as apposed to an upgrade. I remember very well how that benefits Window's upgrades. I only had problems with Windows upgrades and always did full clean installs. But in Mac Land, I just don't see how all the trouble would even be of much benefit if any at all.

    Other than needing to add much needed RAM to my iMac, my Mac works beautifully. Most of the "issues" I was having I learned a way around it or was "tinkering" too much. (I couldn't help it, this is my first Mac!) I've learned to not 'mess' with the settings too often and not get over zealous in keeping my system "clean." Oh how I don't miss the horrible DEFRAG. Although I do love to personalize the icons, dock and such.

    When I upgrade, probably next month, I'll just back it up like I always do anyway. Besides I have one of the new iMacs, it was built for Lion.

    I never do a clean install of my iphone every time a new update appears so upgrade it is. Besides it's just to much trouble reinstalling everything again, register apps, etc. (App store apps are easy I'm taking about other outside the App store). You know how much bandwidth it will take to re-download everything, what will Comcast think! But joking aside, if it does not work you always have the option to clean install.

    I'm basically doing a clean install, since I like the "new" feeling.
    Get rid of all the trash, and get a fresh computer. :)
