With so many existing hits to refine, Apple (AAPL +2.1%) is probably done with new products lines for at least 2011, says Piper Jaffray. The focus will be on new versions of the Mac, iPad, iPhone and iPod. But it's likely Apple will introduce cloud-based iTunes streaming services this year - possibly supported through its new datacenter.
