Since the link focused on the negatives, I'll throw some positives out there (coming from a San Jose native who has lived in SF, LA, Chicago, and now Morgan Hill - mushroom capital of the world).
1. There are some cool little neighborhoods in the San Jose metropolitan area: Willow Glen, Rose Garden/Burbank, Campbell, Saratoga, Almaden Valley.
2. Good ethnic food, especially from Latin America, Vietnam, India, and China. Even some good fine dining opportunities (La Foret in New Almaden comes to mind).
3. A great Latino/Chicano cultural scene.
4. Decent transit that's been getting better (much, much better than LA, lagging a little behind SF and WAY behind Chicago/New York).
5. Retail tech stores all over (even SF lacks this).- Central Computer, any number of Fry's.
6. A developing downtown. If you'd been here ten years ago, this place was dead. If you'd been here 20 years ago...well, you wouldn't have been downtown. The fact that you can go there at night at all now is AMAZING considering what this place was like when I was a kid. It's fairly jumping now, with a decent selection of restaurants and good parking.
7. Cheaper than SF by a bunch.
San Jose is great, especially if you aren't into the trendy hipster scene and don't mind heading into "scary" (aka non-Anglo) parts of town like East San Jose, Little Saigon, etc.
