What I like in Spring 

1. Spring IOC - Its all about programming to Interfaces, Though some people argue its a over kill

4. Spring Data
5. Spring Transactions
6. Spring Scheduling
7. Spring support for JAX-WS
8. Spring AOP
9. Spring Testing - Ability to test Transactional objects and rollback

What is like most in Spring 3.x

1. Annotations - I hate XML, i don't have to switch files (xml and java) to finish my java class and bug free.
2. @Async - love this, you can use this in many situations specially sending Emails. 
3. @Timer - Simple and great Timer implementation,
4. @Cacheable - Dead simple method cache implementation, other alternative is to use Spring Modules framework's which has little complex configuration
