Sell a few AAPL shares and buy CRM?

$Apple (AAPL.US)$ $Salesforce (CRM.US)$ I've got about 5.5% AAPL and 11.1% MSFT. I'm thinking of adding some CRM since I dont have any and don't see much appreciation in AAPL at least short term.

My AAPL shares in question are in my ROTH so no taxes. Should I cut AAPL to 4% or so and diversify into CRM?

I notice CRM at the top if many growth funds and indexes, below AAPL and MSFT of course.
