personally I wouldn't get one, I'd spend the little extra and get one with a slightly larger screen and therefore keyboard too. but that is personal preference, your best bet is go into a shop and have a look at them and see if you think you'd be comfortable typing on the smaller one.
I also don't think the dell mini9 at that price will have a hard drive in it, so it will have very limited storage space.
if you goto pcworlds website, click netbooks at the top of the page and then on refurbished netbooks they have some quite good deals
