do Samsung netbooks count in your query? if so, my wife's using a N220 Plus netbook as an alternative to our bigger laptop... convenient to bring around...
noticeable delay compared to laptop/notebook... other than that it performs very well...
meron na ata mas bagong series neto released recently.
In the netbook category, Samsung is well known for their build quality. No flexing whatsoever. That fact and the matte screens (importante ito over time, trust me) helped propel it to #2 spot just behind Asus in the netbook category. In fact, most online reviews pit a Samsung netbook vs Asus netbook.
Seems like Acer was left behind. Still, I love their Timeline 1810T series. If you can spare a bit of cash, ULV processors have my thumbs up. Intel Atoms bottlenecks performance way too much IMO.
