I always like to have a peek at lists for something I may have overlooked (ooh, shiny!). This one is actually pretty good -- recommends a number of quality items. The average person here may already be familiar or have their own alternatives, but this list might make a good pass-along to less geeky friends.
Gina is an awesome, thoughtful writer - no idea why she's writing for PCWorld though. This should have been on lifehacker or a publication that isn't dying.
PCWorld probably pays her more. This list easily could have gone on lifehacker, but I'd also say most of lifehacker's readers would already be familiar with the things on this list.
Ideally the value of Gina of PC World over some underpaid blogger at Lifehacker is that we assume she's actually reviewed each of these, weighed the results then wrote the article.
Honestly, I bet she makes more at Lifehacker than PC World.
It's on PC World because she got paid for it.
I'm all for top-notch information like this being spread to the greatest audience possible.
