Get the i7, upgrades are getting pretty cheap. I recently for 8GB of ram for 90 with a $20 mail in rebate, plus selling the 4GB to a friend so it comes out pretty cheap.
 
- mid and late 2007 MBP update
- early and late 2008 MBP update
- early and mid 2009 MBP update
- 2010 was the only time there was just 1 update (recently)
- early 2011 MBP updated - seems quite likely there will be a late 2011 MBP update in the September - October time period.

Perhaps research before posting. :cool:

Then there is the Mac Buyer's Guide on this very site: MacBook Pro - Neutral - Mid-product cycle

Technically they did update the 2010 MBP. They offered faster BTO CPUs. It was a "silent update" though.
