All the netbooks are pretty much similar as they're all using the same processor and have similar ram and hd sizes. So not a lot to split the difference between the Lenovo, Samsung, Fujitsu, HP etc etc barring price.
Apparently, the U101 only comes with a 3-cell battery BUT Benq will send you an additional 6-cell after you purchase. I'd like to hear what owners have to say too.
