I reviewed the P1610, and I hare been playing with one for around a week while I was preparing it for a customer. And so far the only thing that I don't like is that the screen it's a bit too "spongy" for my taste. But God! It's so hard to not fall in love with these Fujitsus! And now this one announced today by Engadget.
It's not the most powerful convertible in the world with a max configuration sporting a Core Solo U1400 proc and Intel GMA 950 graphics. What it lacks in power however, is more than made up for in portability: 8.9-inch, 1,280 x 768 LCD; up to 32GB SSD or 80GB disk; up to 9.1-hours on extended battery or 4.3-hours in a wee bit of kit weighing just 2.1-pounds. Windows Vista Business will cost ya ¥270,000 (about $2,188) out the gate.
Check this, 9 hours of Battery Life with XP and the extended battery! that Probably will be around 3 hours on Vista with the original battery.
