I like Intel’s Montavello 1 prototype — I think it was originally rumored to be a tablet PC (i.e. the screen would also fold back), and it would have been even better, but even as a simple laptop is a nice configuration.
Cool Ajax trick: Windows Live’s infinite scrollbar (see? I can say nice things about Microsoft!) — although, being that it starts and rests in the middle rather than at either end, the appropriate metaphor would be more of a jog-dial. Much more seamless and intuitive… uh, maybe not… pleasant? well, more fun, anyway, and web 2.0, than clicking “Next” over and over again to scroll through long lists. Perfectly applicable to search results, virtual rolodex, blog archives, you name it, and I’m sure it could even work on Safari, if you wanted it to.
Yojimbo has been updated to version 1.1, but it apparently doesn’t extend my trial period, so I can’t test it. (To their credit, the expiration notification offers me to export my Yojimbo library, that’s nice.) But it doesn’t look like the improvements address much of my gripes anyway (actually, they don’t seem to be quite worthy of a point version increase).
