Lack of Product Placement and Integration
MS should learn a lot from Google how to place, promote and better integrate services if it wishes to compete better with Google.
1. Open Google.com - A big Google Chrome Direct download One click button.
2. Download and Open Chrome - A Big Fat Gmail icon in front of your eyes to create a Google Account and Sync Browser settings
3. Create a Google Account - Bammm. now you are a Google Plus User :) with a Gmail account and Chrome as Default browser. You also have a default Google Drive account as well.
This is just a small example of product placement and integration, if you go inside Google, there are a lot of other excellent examples.
Google started with just Google.com as has cracked a huge market share now for Browser, Email, Social and many other areas. MS should learn a lot if it wishes to be a next gen services company.
