Wil DuBois at LifeAfterDx has received his new Gen4 system and will post his experiences and opinions at his blog: http://lifeafterdx.blogspot.com/
For those of you who are not familiar with his blog, Wil was one of the first people to use the first Medtronic CGMS many years ago and wrote extensively of his experiences with it. In recent years he's addressed many topics that encompass his diabetes, various pumps, CGMS, his family, his job, etc. He's a fabulous writer and I suggest you read his old posts as well as the current ones. He doesn't post daily on his blog anymore, although I suspect he will with the Gen4 review.
