You have opened a big ol' can a worms with this question. I have no personal experience with owning any laptop, but I can tell you what my clients tell me. That is, the way to go is Toshiba because of their reliability and customer service. I have had too many client buy their next toshiba lappy saying that the only reason they are upgrading their 8 year old lappy is that it cant run any of the new software.
Hope this helps. Do some more research and listen to what people say about their own experiences. And then make the best, informed choice for YOU.
