My desktop at home died a few months ago, and I've decided to replace it with a laptop. I've never had a laptop before and, despite this whole blogging thing, I am far from technologically savvy. Looking to spend less than a grand, and sorry Mac lovers, I'm sticking to PCs. Any recommendations or things I should know, like about batteries, wireless cards, or whatever? I've had decent luck with Dell computers in the past, but I may be able to get a lower price on Sony or Lenovo.
