My opinion of Dell has varied over the years between “meh”, “Bleh!”, and “I would rather have Syphilis!”. They are not that great on reliability, and are sometimes harder to work on. I still recall their use of non-standard power supplies that lead to many people frying their motherboards :p
Personally, I would go with a Toshiba laptop. They are more reliable than Apple, less expensive than Dell, and just plain better overall.
@YoBob I agree that casting off the Microsoft yoke is a good thing, but you seem to forget that not all PCs run Windoze. You can get the good parts of OS X with a Linux rig for far cheaper. Don’t forget that both Linux and OS X are UNIX-based OSs, and if the Aqua interface is so important then you can use Mac4lin. Also bear in mind that the newer versions of many distros are designed to be n00b-friendly and simple; you don’t have to be a wizard to install and/or run Linux like you did ten years ago; you merely have to be intelligent enough to know your name, what time zone you are in, and what language you speak. After that, it isn’t really any harder than OS X.
As for the cloud, I think we have a long way to go before that can be done trouble-free, and there will always be people like me who want our info kept locally instead of somewhere where anyone can get to it. That doesn’t even get into the possibilities of crashes like T-Mobile had that can wipe out (or at least lose access to) the data of millions of users.
