This is a clipping from the DTE power outage map pulled at 11:15pm on Saturday, 25 April 2009. If you have a network connection, you can get your own copy (as a PDF) from their web site.

It will take at least a “couple of days” to restore power to customers, he predicted.
Damage from the storm in Oakland County was extensive.

Brighton, MI was hard hit in the first wave of storms, with soccer games cancelled or cut short and kids running for cover, per a conversation with a friend who was one of those who ran for cover.
Lansing Give Camp had a complete power outage, per @jayharris:

All in all a typical summer thunderstorm with trees down, some dislocations and network failures, and quite a few adaptable people.
