Pros
Boise is a nice town to live in, especially for the young professional. There is hiking, biking, whitewater, and a nice downtown area. I especially enjoyed having the foothills so close and did numerous bike rides and other activities nearby. Micron offers an above-average starting salary, especially considering that Boise is a very cheap place to live (compared with Silicon Valley).
Cons
Micron is in a difficult industry and has been struggling with commodity RAM pricing. It competes with Samsung which is head and shoulders better at making memory. I found the memory business to be less exciting than other semiconductor businesses. Micron is trying to diversity into other areas besides memory, but they aren't seeming to get a good foothold in any other sectors.
