|"Which laptop should I buy?"|
Neither of them are laptops. And the next time you post a link, please leave a space before & after, otherwise it ceases to be "clickable".
ASUS Eee PC 1015PEM-MU17-WT 10.1-Inch Netbook
Toshiba NB505-N508BL 10.1-Inch Netbook
I'm guessing you're basing your choice on price & not on features? Of the two, the Asus is better. Personally, I wouldn't want either one of them. I don't know where you're from (Canada?), but in the US, you can buy a REAL laptop for not much more. And I would be VERY careful about dealing with that site. It was only registered a few months ago & the registrar's name is "Caleb Snickerbar" with the email address "wackjackoncrack at hotmail dot com"

If you are from Canada, check out Newegg:
