The VivoTab RT 32 GB on sale

I don't know if this applies to Microsoft Store outside of Canada, but i went to the Microsoft Store last Sunday (My first time going to a Microsoft store, and I felt like a kid in a candy store - I'll probably make my thread for it because I have pictures), and I found out that the ASUS VivoTab RT 32 GB is on sale for $399 + the keyboard for free. The original price was $599.

Do you think it's worth it? I have $25 dollars in my bank account, but I can only dream of getting it by Dec. 31 :(
