Rather than trying to decide upon a brand, you should be looking first and foremost at what you plan on doing with the laptop and thus what you need for the laptop to have in it.
Also, be advised that if you plan on paying less than $500 you better plan on getting a laptop that has been skimped on in some way- RAM, older processor, etc. - if you don't mind upgrading in a year or so when it starts to run slow as molasses (and I don't mean b/c of installed programs / the need for spring cleaning, I mean b/c it simply cannot keep pace with the current processors out there) then by all means buy a cheaper laptop. If you want it to last without you screaming bloody murder in about a year b/c of the fact that it is just slow, consider investing (wisely!) in a decently priced laptop with some power behind it.
Lenovo is great for the average business user - but if you want all of those bells and whistles on it, for example, to make / edit video clips for, say, a school project, then you might consider avoiding a business line of products. After all, not everyone is a business person. And, yes, school projects do, nowadays, involve more and more video editing and creation than ever before. To dismiss such functions as flashy multimedia and worthless is taking a very narrow view of the use of a laptop - not everyone has the same needs as GrdLock.
