While I'm getting screwed with MobileMe at the moment, you're entirely incorrect on those.
I renewed SIX DAYS AGO, and my account is still fully working, and will continue to, through June 30th, 2012.
As a dev, I'm setting up iCloud right now, with a fresh Apple ID. MobileMe accounts aren't supported for transfer yet.

Introduction
This document offers instructions on how MobileMe users can copy data from an existing MobileMe account to an iCloud account. If you experience any bugs while you are migrating your data, please file a bug report using the Apple Bug Reporter.
Important note for Shared Calendars: Calendar sharing requires an iCloud account for all users. If you manually move your data to iCloud, you must re-share any calendars. (Calendars you share in MobileMe will be unaffected when you manually copy your data.)
Copying data to iCloud on iOS 5
Before you begin, itʼs important to make sure your iOS device is updated to iOS 5 beta, and your MobileMe account is configured and currently syncing your contacts, calendars, and bookmarks. You will need to keep this data locally and then upload it to iCloud. The data in your MobileMe account will not be affected by these steps.
Step 1: Download calendar data older than one month (optional).
By default, your iOS device stores one month of historical calendar data. If you want to migrate calendar data older than one month to iCloud, follow these instructions. If you donʼt need to move your older data, skip to Step 2.
Begin by connecting to a Wi-Fi network (using Wi-Fi is recommended). Tap Settings > Mail, Contacts, Calendars, then scroll down to the bottom and tap Sync
Choose how much of your calendar history you would like to download and transfer to iCloud.
Open the Calendar app. You will see a status wheel in the status bar. Wait until the wheel disappears, this indicates that all your data is on the device. It may take several minutes for this process to complete depending on how much calendar history you have.
Verify that all your calendar data is now on your iOS device.
Step 2: Turn off MobileMe sync and keep data locally on your iOS device
Tap Settings > Mail, Contacts, and Calendars
Select the MobileMe Account.
Turn off each of the following one by one: Contacts, Calendar, Bookmarks, and Find My iPhone. Mail and Notes can remain enabled on your iOS device.
When prompted to do so, choose to keep the data on your device.
Step 3: Setup iCloud Account
Tap Settings > iCloud
Sign in with an Apple ID. You can use any Apple ID you already have so long as it is a full email address and isnʼt a MobileMe account. If you already have an iTunes Store account or a free Find My iPhone account, you can use that Apple ID as your iCloud account. Or you can click Create Apple ID to create a new one.
Follow the onscreen instructions to finish creating your iCloud account, and then enable the services you wish to use with iCloud. The data you kept locally in the previous step will be merged with any data already on the iCloud servers.
Go back to Settings > Mail, Contacts, Calendars then scroll down to the bottom. Tap Sync and change your calendar history setting back to 1 month for better performance.
Troubleshooting Tip: If you see duplicate events after the first upload, check Settings > Mail, Contacts, Calendars and remove any manually entered CalDAV accounts that have cal.me.com as the server.
Copying data to iCloud on OS X Lion
Before you begin, you will need to install the latest version of Mac OS X Lion Developer Preview, and install the iCloud for OS X Lion. Make sure that your MobileMe account is configured and currently syncing your contacts, calendars, and bookmarks. You will need to keep this data locally and then upload it to iCloud. The data in your MobileMe account will not be affected by these steps.
If you wish to test Photo Stream, you must install iPhoto 9.2 beta. You will need to export your photos, reinstall Mac OS X Lion Developer and iPhoto, and then import your photos.
IMPORTANT: The iPhoto update will replace your current version of iPhoto. Your existing iPhoto Library will not open with this version of iPhoto. For this reason it is strongly recommended that you work on a test/development system only when using this release. You will not be able to revert the system to an earlier version of iPhoto without doing a clean install of Mac OS X and reinstalling iPhoto either from your original installation DVD or by downloading from the Mac App Store.
Step 1: Turn off MobileMe Bookmarks, Contacts, and Back to My Mac.
In Lion, Open System Preferences.
Click MobileMe, and sign out of MobileMe. Your bookmarks and contacts will automatically be saved locally.
Note: You may use OS X Mail with both iCloud and MobileMe accounts at the same time.
Step 2: Export your calendars (skip to step 3 if youʼve already transferred your data to iCloud from your iOS device).
Launch iCal, click the Calendars button, and select a calendar. In the File menu choose Export > and save the file. Repeat these steps for each calendar you have.
Step 3: Remove your MobileMe account from iCal.
Open iCal Preferences. Click Accounts, and select the MobileMe Account Click (minus button), and click OK.
If you exported iCal calendars in Step 2, double-click each saved file and choose "New Calendar" from the drop down menu to import them to On My Mac before you sign in with iCloud.
Step 4: Sign in with your iCloud Account
Open System Preferences.
Click Mail, Contacts, Calendars and then click Add account.
Select iCloud and sign in with the same Apple ID you used on your iOS device. If you did not start with your iOS device, you can use any Apple ID you already have so long as it is a full email address and isnʼt a MobileMe account. If you already have an iTunes Store account or a free Find My iPhone account, you can use that Apple ID as your iCloud account. Or you can click Create Apple ID to create a new one.
Follow the onscreen instructions and then enable the services you wish to use with iCloud.
Copying data to iCloud on Windows
Before you begin install the iCloud Control Panel for Windows, the iTunes 10.5 Seed, and the Safari 5.1 Seed if you are running Windows Vista or Windows 7.
Note: iCloud Calendar and Contacts require Microsoft Outlook 2007 or 2010.
Step 1: Save Calendars locally (skip to step 2 if youʼve already transferred your data to iCloud from your iOS device or Mac).
Open Outlook Make sure only the first of your MobileMe calendars is checked in the Calendar list.
Choose File > Save As. Adjust the save settings to include the whole calendar (this will vary depending on your version of Outlook), and save the calendar on your computer. Repeat steps 2-3 for every other calendar you want to save.
Open the MobileMe Control Panel and disable the Calendar checkbox.
Return to Outlook.
Choose File > Open and select your saved Calendar file to import them as a local calendar. Repeat for each calendar you saved in step 3.
Step 2: Sign out of the MobileMe Control Panel
Open the MobileMe Control Panel and sign out.
Step 3: Sign in with your iCloud Account
Open the iCloud Control Panel. Sign in with the iCloud account you created from either an iOS device or Mac running OS X Lion.
Follow the onscreen instructions to finish signing into your account, and then enable the services you wish to use with iCloud.
