You get used to the smaller screen size. However, for many applications, having at least 1280x1024 is a must and a lot of websites and applications aren't coded to handle smaller sizes very well.
Personally, I'd recommend getting a business class laptop.
From a quick look at the Lenovo website, they've got a fairly good number of laptops with resolution like you want, with a fairly good selection of price points. Oddly enough while the US site allows you to select by resolution, the UK store doesn't.

Want to grab a laptop myself, my sister is traveling to the US soon and I was thinking of having her bring one back for me. Haven't picked up a new laptop since 2002 so I would appreciate some recommendations (I'd be buying it online and having it shipped to her).
I don't play many new games, though I would like for it to be able to run most of what's out today and what's coming out in the foreseeable future. Also, would really prefer Windows 7. Seems every website I check they only have laptops with Windows 8.
Try looking for a business class laptop. Often times they don't cost any more than the basic models, but I know that Lenovo is still offering 7 on their laptops.
