Most consumer level machines are garbage. Dell is generally worse than others, especially for out of the box failures. They use some of the cheapest materials of any PC manufacturer. In meetings I have had with their engineers and salesmen they have admitted as much. I have been supporting laptops and desktops alike for over 10 years. Don't be so quick to speak on a subject that you apparantly have limited experience with.
I have worked with IBM's, HP's, Dell's, Compaqs, Gateways and a few others. I have to say the cheapest and most unreliable of these machines were Dells. Understand that the majority of my exposure is to business class machines, which, by the way, are generally more reliable than their standard consumer level products. The most reliable manufacturer of machines I have worked on in my 10 year work history are IBM and Compaq. No one, at least in the last 10 years has made a more reliable business product. Compaq's support of their product in the way of keeping up with drivers and such was particularly awesome. Their hardware was robust and reliable. That being said I would not buy a Presario line PC unless my life depended on it (EG someone held a gun to my head). Not so much because of the quality of the product, but more because of the proprietary nature of the software and OS build. They can be a pain in the *** to work on as they don't generally offer the same level of support with regards to drivers etc.
Dell picked up Alienware didn't they? Their XPS line has seen some improvement as a result. I would hardly call their XPS line a consumer level product, at least in the way I am attempting to classify them. They are a 'gamer' line of PCs and typically have better hardware in them.
Has anyone experience with any of the Asus branded laptops or any of the other smaller manufacturers that generally make top end PC parts (motherboards, video cards, etc)
Good advice to anyone buying a laptop to play games: Buy a laptop that is built for gaming! They are generally more expensive, but then, you usually get what you pay for.
IMHO - Try and give the OP what he asked for, constructive critism and advice, don't be slamming his gear. He wasn't looking for your opinion on the quality of manufacture, he wanted to know if this game will play on his PC.
FOR THE OP - I would have to say that yes it will play fine. WoW isn't particularly 'hard up' for top of the line graphics cards; obviously having a better graphics card will make for a better game playing experience with regards to the 'eye candy', but not everyone is focused on this. Do, however, ensure that you have a decent amount of RAM. I would say that 2GB is the minimum. Being that it is shared memory you might opt for more. Memory is super cheap these days though, so fret not if your laptop is not up to par :) If you must buy memory, I would advise completely replacing the memory that is in the machine currently with the fastest memory you can get for the money, but DO NOT throw it away as if you need to get the machine repaired under warranty, you MUST have the original memory in it. If you buy only 1 chip and add it to your current machine, the bios will set the memory speed to be the lesser of the two different sticks. You also risk (although this is fairly rare) memory incompatiblity. Dont settle for the cheaper stuff, 2GB is like 40$ anyhow, dont save 8$ for the 32$ set as it is signifigantly slower) Low CAS latency and high memory bandwidth are what you are looking for. Make sure that your PC will support it, most manufactuers list compatible hardware, but to be honest, memory compatibility is usually not an issue outside of buying the wrong TYPE of memory (DDR as opposed to DD2 or DDR3 for example).

Celeron processor is not the best option, unfortunately, but it is not likely that you will notice. Multitasking is probably going to be a problem for you though :)
Never give a man a shot in the pills, baby, that's just not cricket!
