Planning to use TrueCrypt to protect drives on our desktop and laptops, and looking for advice about laptop choices in light of that. I'm going to be getting a new machine this summer, and I'm comparing netbook like the hp dm1z vs. low-end Sandy Bridge machines for my wife (who wants a 12" that she can fit in a slash-proof purse). The dm1z seems perfect for her needs, but the speed difference in TrueCrypt between the E-350 and a low-end SB processor (in some machine coming out at some point - I have a couple months) gives me pause. I understand setting TrueCrypt up on the dm1z would be significantly slower, but would it also create a noticeable difference in everyday usage? I'm a bit concerned; if I'm already looking at a netbook or low-end laptop, I don't want my encryption program really slowing it down.
Thanks for any advice!
