OSX Lion: Should you upgrade?

I love upgrades.  I am usually the first one to get a new operating system, an app update, or the latest beta version of a software.  Half of the software that I run on my various devices is in beta.  I love being on the cutting edge.  Sometimes this means you get the latest features, and sometimes you get some broken stuff.

Apple on Wednesday released "Lion" the latest and greatest update to what it calls "The best OS we've ever made".  I've checked out the reviews, watched the videos, and I think it looks fabulous.  Take a look for yourself:
With every major upgrade, there is the potential for stuff to get broken.  I almost updated right away, and then I thought I should do a little research.  A few Google searches later and I came up to this post by a Google employee on the Sketchup help forum:

On behalf of the SketchUp team, I want to give everybody a heads-up that we've encountered a few issues using SketchUp on the new Mac Lion OS. You can check them out below (along with suggested workarounds); we are working on improving/fixing these -- thanks in advance for replying here with any other issues you find using SketchUp on the new Mac OS!

Issue: SU freezes when generating scene thumbnails for models with background images (ie, those with Match Photo scenes).
Workaround: Keep the Scenes dialog box closed when working with models with background images.

Issue: In a model with 1 match photo scene, the camera is no longer synced back to the scene when clicking on the scene.
Workaround: Add a second scene via some method other than using the Scenes dialog - e.g. right click on the Scene tab and select “Add”. Adding a scene via the Scenes dialog is not possible given the first issue.

Issue: When trying to login to the 3D Warehouse from within SketchUp, you see the message “Service not available. Try again later”.
Workaround: You can still login to the 3D Warehouse outside of SketchUp by going directly to the site: From there, it is possible to then upload KMZ files which means you need to export your SketchUp model to the KMZ format before uploading.

Issue: When selecting a region using the “Photo Textures” dialog, only one pin is visible which makes it hard to accurately grab a photo texture. You can still grab photo textures - it is just that grabbing the exact region you want is now more difficult as you can’t see all the pins.

Workaround: By left clicking on the photo region and moving the mouse, you can somewhat manipulate the region you want to capture.

Issue: With the new Lion OSX, there is a new Mouse option (“Move content in the direction of finger movement when scrolling or navigating”) which is checked by default. When this option is checked, scrolling forward with the mouse wheel causes the SU model to zoom out and scrolling backwards causes the model to zoom in.
Workaround: In Lion, go to System Preferences > Mouse and uncheck “Move content in the direction of finger movement when scrolling or navigating”. Note: in a future release, unchecking this option should no longer be necessary.

Issue: Stacked Snappy dialogs can now break apart after resizing one of the dialogs in the stack.
Workaround: Re-snap the dialogs together if they break apart after a resize.

Issue: With Lion, SketchUp now remembers whatever models you had open in a previous SketchUp session and, on re-launch, opens those same models. This means that models can now show up behind the Welcome dialog, which is a change of behavior. It may also mean that SketchUp can take longer to launch and may potentially re-open a problem model from a previous session.
Workaround: Close your models prior to exiting SketchUp if you do not like this behavior.

So, I suppose not an entirely bad list, but there are a few alarming ones in there, particularly with the 3D warehouse.  No official word from Google on when we will see some updates.  So those out there itching to upgrade, you probably should let Snow Leopard purr a little longer.  Have you upgraded?  Tell us your experience in the comments!
