I don't get it. What's the point? You can already save full webpages to your disk using safari. Just click file > save as > web archive.
So all this feature does is give you a bookmarks folder that you can access from different computers? A small number of people would find that useful, but I imagine that the vast vast majority of people would have absolutely no use for it.
Don't generalize and assume what people will like or not like. Instapaper and ReadItLater are very popular for a reason along with Pinboard.in and other services like it.
As MR already explained in the article, this is just a different kind of bookmarking.
There are some people who just bookmark links to revisit it later in the short term and there are some people who saves a copy of the web site for long term storage. Sites change all the time, there is no guarantee that a link will still work a week from now.
We also have no idea what it actually looks like. It may be a combo of Reader/WebArchive, where users can also switch between the Reader/Web versions.
This is just another feature for some users and it's not forced upon people who doesn't find it useful.
I guess I can see what you're saying, I suppose that would make it slightly easier since it saves you a couple of clicks. But still, that hardly makes it a special feature. It's basically just a "save" toolbar button with a default save folder location.
I suppose that might be useful to some people in some situations. But I think the vast majority of people would be just as happy syncing their regular old bookmark lists.
And they'd still be able to do that. This is just a bonus feature for certain people who prefer saving copies of their bookmarks instead of links.
This isn't a special feature, nobody is saying it is. MR is just reporting on what they found new in Safari and Lion. Yes, it's a minor new feature but it's still new.
