Choose the apps—like Notes, Photos, and iCloud Drive—that you want to use with iCloud. Apple OS X (10.6.8) is not supported with Apple iCloud, but Apple claims that the desktop Mail app will remain functional. Even though users have moved supported devices over to iCloud, Apple still asks the user with an old 10.6.8 to move over. Lastly get an iCloud account (it's free now) because it is IMHO much better than the old Sync of MoblieMe between Apple devices. It is not like a DropBox but think it as more as a device syncing service (enough though it is a little more than that). IMHO WARNING: Don't import Network setting from 10.6.8.
For the best iCloud experience, make sure your device meets the minimum system requirements.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mavericks if your computer meets the requirements. In response to rhodeia. As someone who just purchased a 17' MB Pro 2.3GHz core i7 Processor running OS X 10.6.8, I think it is downright thievery for Apple to require me to purchase a new OS in order to run iCloud. Especially considering iCloud is a service Apple expects to charge a useage fee for (for storage over 5GB).
