I'm using a fujitsu u810, and I'm very satisfied; it's 2 years old now, and even it's still performing very well, I'm looking for a replacement (geeks need to change toys sometime ...)
With the u810, I find suspend/resume very nice, just something like 5secs each, and extremelly robust; my last uptime was 35 days!!, suspending once or twice a day!!
It has 5'' tablet touchscreen, and battery wise is about 4/5 hours with the extended battery that comes as default.
Now I'm looking for an ultraportable notebook (not netbook), since I got a little tired of underpowered computers, that don't allow me running powerful development tools nor other os emulation.
