Give it a few more months and you'll likely be able to buy a Yonah-based Powerbook that is capable of running whichever charting apps you desire at nearly full speed in a VirtualPC window.
I assume it is the Intel powered Mac to arrive in 2006. http://www.tomshardware.com/hardnews/20050602_143758.html
Sorry, Yonah is the codename for Intel's next generation of mobile CPUs (current gen was codenamed Sonoma). Most Yonah models will be dual-core. Apple is going to be switching to Intel processors beginning sometime in 1st half of 2006, current speculation is that Apple is highly likely to update their mobile line-up with Yonah processors.
