It's an alpha guys, Opera Software has clearly stated the full feature list will be unveiled as 2009 rolls along. At least one thing it'll surely get is a redesigned GUI, hopefully a *new* one instead of a light facelift with a different skin. Jon Hicks is working on it, so I expect great things there.
As for the features, there's nothing other browsers already have, even in the web standards department, BUT, they included some things long desired by the majority of users, so props to them. Also, it may be just me, but it seems like they're changing Opera's development method quite a bit, rolling out big features with each major version (alpha x, beta y, etc.), and fixing bugs in the weekly builds, instead of fixing and rolling features as they go, like it happened before. More Firefox-like, which hopefully it will be better for the overall quality of the final product (so I don't have to rant again :P)
