So you have Windows 8 and now you want to use the cool Calendar and People apps on the start screen. But, you want them to sync with your Android phone (or iPhone). What is the best way to get them to sync?
At the time of this writing, there is only one way to do this: Use Hotmail/Windows Live/Outlook.com accounts at both places. For the sake of brevity, I will only refer to Hotmail from now on, but understand it also means you can use your Windows Live or Outlook.com account as well.
Hotmail is the preferred method of syncing things in Windows 8. You can use your Hotmail account to sync email, calendar, people (contacts), and documents (through Skydrive). You can also use this same Hotmail ID on the Android (or iPhone) to sync the same things. If you don't have a Hotmail account yet, sign up for one with Microsoft. Then set it up in Windows 8, allowing it to sync mail, calendar, and people. Then set up a mail account on the Android using the Hotmail account. The type of account will be an "Exchange" or "Activesync" account. I have personally found this to drain my battery excessively.
Alternatively, there is Microsoft app available for the Android called "Hotmail" that apparently does not have the battery drain problem and does the same thing as setting up the mail account locally on the Android.
Of course, you can also sync your Hotmail account with Outlook as well. I have written a full review of the process at syncdroid.net/hotmail
Finally, you can also install the Skydrive app on the Android so you can have your documents in both Windows 8 and on the Android (or iPhone). There are also other document sharing solutions like Google Drive and Dropbox, but Skydrive is built into Windows 8 already.
I realize I have not gone into great detail here and there will be a lot of questions. Do you have another or better idea? Let us know!
