50g

Hi!

Every now and then i check out the hp website, and see some of those new 
financial or scientific calculators. I'm a 50g owner for a year now. I 
was wondering, since 50g has some financial  functions (tvm, amor,..), 
is there anything these financial calculators can do, that 50g cant? 
(And i mean that, out-of-the-box, without special programs for 50g)?
Since i'm an engineering student, I never even tried calculating 
anything financial, so that's why I'm asking if there are things where 
financual calculators beat 50g (except in size and price :))
