I have had several Acer netbooks and notebooks all have been fantastic. I have a 532 with 2bg ram and a SSD this is as fast as my acer notebook core 3 with same ram and SSD. My old notebook lost its battery charge and tried several times to get a replacement in the end stripped it down sold the bits for about the cost for a i3.
My netbook I upgrade every 2 years sell the old one add £40 difference to get the next model up for around £140 this way I dont get battery issues.
2GB ram is a must and so is a SSD. yes you loose some storage, so put the old HD in a portable usb case and watch it fly.
I have noticed that a lot of these now are 3 cells, cant be doing with that.
These devices are more than capable of surfing and office work, ok serious spread sheet or autocad then its a pc with masssive monitor, (saying that add a usb mouse and plug into hdmi TV way you go) but I like the keyboard so noooooo to touchpads and windos 8
