I just chose the N150 because my color and keyboard were not so important. The N220 has a keyboard we we know them from the MacBook. I have Windows Starter to Windows Premium upgraded. And 2GB of RAM I have. For me, all expectations were met exactly. I want a netbook Train and university because of my 15 inch chunk was too big. The battery life is in spite of a small battery TOTL sufficient for me you can easily watch 4 hours movies and surf the internet can accommodate up to 6 hrs. (Here the N220 has a larger battery). One can enjoy all Office applications and things like Itunes, Skype, Messenger, etc. Easy and liquid. If you let more things run simultaneously you quickly realize that there is a netbook and not a laptop is then everything is a bit slower.
To look I can only say it is simply the red line is very nice and the keyboard is similar to the MacBook but Not quite as good. The touchpad responds well and you can control it with 2 fingers. Important for my purchase also Bluetooth was because I prefer to use a Bluetooth mouse and any USB transmitter can suffer nich. For headset and mobile phone, it is also practical. Who can do without it also has a larger selection of comparable netbooks.
All in all I am very satisfied and can only recommend it but you have to always be clear about what a netbook can. Then you will not disappointed.
If you have further questions just ask;)
