Finally, the one thing that does bother me - beer in tech companies usually means they want you to be there 24/7. Fine, ok - but you can do business elsewhere.

This is very true, and includes other benefits too. Dinner is a cheap price for a few hours of developer time. Laundry service? Much cheaper than a few hours of developer time. Package delivery at the office? Again much cheaper...
