You think laptop thieves will read the blog and start stealing brown paper bags on the off chance there's a laptop inside?

To me it seems like a pretty good strategy, with the downsides being you have to lug it around by the handle (no back or shoulder strap, which would spoil the camo effect), and it doesn't have pockets for small things like cables / dongles / etc.

I won't make that claim but I do think obscurity tactics are not normally publicized.
