Hi Sue The answer to buying a laptop (or any computer) is realtively simple; buy the best that you can afford! Neither N6 or Nvivo are particularly power-hungry applications and any current spec laptop should be fine. It's more important that you consider quality/reliability of the product, how you will use it (if you travel a lot, focus on light weight; if you just move from home to office, maybe that's not the big issue). What about connectivity (to a network, wireless, Internet access - how, when, where?). How will you back it up (if you're not networked, consider a CD-RW as critical!). Have you used laptops before and liked or disliked particular things about them? Is battery life an issue or will you be on mains power most of the time? Also consider the warranty and the suppliers reputation. Too often we focus on the technology but 9 times out of 10, the real issue is what we want to do with that technology; what will work *best* for me :-) Hope that helps! Andy BTW, I use Nvivo on my laptop (Dell Inspiron 8200) and it runs fine, no different to any of my desktop PCs.
