Hey Cheapy and Wombat,
With the release of the new dashboard update that adds more superfluous features and apps that seem to have been shoved into an already full interface, I really started to hope that Microsoft and Sony could take a page out of Nintendo's book in offering a customizable interface. The Wii offers its channels system that lets you put any app on a seperate page so you can organize it however you wish, but on the PS3 and Xbox 360, you have to deal with whatever Sony and Microsoft wants to add whether you think it should be there or not.
The 360's dashboard only has three or four essential tabs (My Xbox, My Friends, Games Marketplace, and maybe Video Marketplace) while the other four tabs should be optional or at the very least you should be able to rearrange things within whatever boundaries MS would want to set since they'd still want to have ads and all that. The new apps are just spread out across the dashboard while adding a new tab or two, but I'd love to ask the people that are in charge of this stuff why they this was the best solution they could come up with. To add to this, you're actually paying for access to most of the features on the dashboard (most of the apps, 1 vs 100, early demos, etc.), so shouldn't you get a say in what your interface looks like outside of the few free premium themes you can get?
With the XMB, it's not so much of a cluttered interface, but the additions of PlayStation Store icons to the Game and Video tabs, the news ticker than runs even when you're offline, the What's New icon, and those kinds of things should be able to be toggled off since they were added for new or ignorant users and everyone else that's fully aware of what is on PSN should have the option to turn them off. The Facebook integration in firmware 3.10 seems to be done well as you go into the options to turn them on and the effects can be seen in the browser, which makes full use of mostly anything that site really has to offer, unlike Twitter on the Xbox 360.
I'm sorry for ranting a bit there, but it seems odd that the system that most gamers probably turn on the least offers a much more flexible interface that you probably use 99% of the time. It seems that as our systems get more complex, feature-filled dashboards, we should have more control over what do and don't want to see so that these systems can fulfill whatever uses you have for them.
Also, for a light question, could you imagine how crowded this holiday season would be if even half of the games that were delayed actually came out when they were originally supposed to?
