Windows 7: Online Banking - PC vs. Laptop vs. iPad 2 or 3 vs. Macbook?

I'm using adsl2+ directly connected to the laptop or pc by Ethernet cable. I don't plan on using wi-fi.


1. Out of those, which is best suited for online banking? Basically which had the least and which will provide more protection for banking online?

2. If i buy an laptop or pc from the computer retailer,

a) Is it best to buy a system that comes from the store or buy separate parts?
I mean if i buy a pc system from here:

How do i know that system will be safe? What do i look for in the specs?



3. How secure is the laptops you buy from a computer retailer such as MSY?

4. If i choose to buy a laptop, do i need to format the laptops hdd and reinstall windows just to be safe?

I only do online banking with my PC. I don't have a Mac, or an iPAD, or any other apple device.

It's best to buy a system if you don't have any idea how to build one, it's often best to build it to get exactly what you want. I've done it both ways, and both ways worked just great.

A system is only as safe as the end-user.
