Well it's 16:9 rather than 16:10, so it's quite wide and not very tall. So maybe text won't be that much smaller than on a 24" 1920*1200. I do prefer 16:10 for general work though myself, it's personal preference though. Perhaps you could look at one in a shop?
If you find that it doesn't suit you, you can always return it under the DSA within a week of purchase, all it'll cost is postage.
