GigaOm touches on the nepotism favor of Dell buying MessageOne:
Is Michael Dell rescuing his little brother, or does Dell spending $165 million to buy email continuity firm MessageOne make sense? MessageOne has a good product, but without the sexy security component offered by Postini or FrontBridge, buyers never picked up the 10-year-old company. So the deal has more than a hint of nepotism.
This is just one move in Dell's plans to offer managed services. It seems Dell and software companies want to move away from one-time buy and deep in to recurring revenue.
