Mini Laptops

I have been so in-love with my dell inspiron duo since I got it 5 months ago. One drawback is it's battery life. I hope to have one with longer battery life; I guess one that will last the whole 8-10 hours. So now, I want to try other brands of mini laptops. I'm currently saving for at least five hp mini laptops that I want to buy and use at work.  Actually something I want my centers group to use at work.  My hubby is also planning on getting one.  We need to wait for great deals before buying.
