I could care less about what map application I had to use, or search engine, so Microsoft or Google, could care less. Every now and then I need a map or perform a search on my phone, not significant for me.
What I have been using Google for regularly was cloud storage of my calendar and my contacts.
That is all changing.
I have already deployed Microsoft Dynamics CRM in my company. Dynamics has the web interface, but Dynamics also runs inside Outlook on my desktop, blows Salesforce away for MUCH less money. Also, the mobile version of Dynamics works perfectly on the Pre. All my business contacts, accounts, opportunities, are always with me.
The next on the list is to move away from pop email on my server, and move to Microsoft Online Exchange. All the functionality you expect from exchange you have always heard about, direct from Microsoft, for $5 a month, or packaged with other business tools for a few bucks more. Online exchange will replace my pop mail, making my email full exchange, and includes cloud contacts and calendar.
I will be dumping Google all together.
