IMHO, a MacBookPro is way too cool for a bank manager, unless he is the
IT Manager, it will probably push him into midlife crisis then he'll go
out and buy a porsche :-)
Here's my reasoning; If whichever non-mac laptop he chooses costs more that 100k, he might as well get the Macbook white @ 105k. Below 100k, I would go with Ngatia's suggestion, but specifically the XPS series. Also, 2GB RAM should be minimum, if he gets 4GB, then he'll need the OS to be 64bit.
But on second thoughts, I would push him to get MBP then sit back and watch with glee as his savvyness shoots thru the roof :-)
