The problem with speaking with a real person is that they may be on a bonus to sell a certain model of laptop, not just the best one.
Some companies, or shops, may offer say a �50 bonus to sell a HP or a Sony so you cannot be sure you are getting an honest opinion.
You may also speak to a good person in PC World or a bad person in Currys so it is pot luck who you get.
I would look at PC magazines, like What Laptop, who give fairly honest reviews. Web site here:

Other PC magazines like PC Pro do regular laptop reviews, so have a look in W H smith at the front covers to see what magazines are doing a group laptop review.

I would also wait a month or so and get a laptop with Windows Vista on it.
If you buy one with XP on it, and want to upgrade to Vista later, you may have all sorts of problems with drivers etc (laptops often require very specific drivers)
