Ultra portable notebook advice

Hi Guys,

I am interested in purchasing a laptop and as you read the subject, my main aim is to make sure it is portable. My definition of portability is light weight and small screen (not too small though).

I am more of a Dell guy and I came across a dell lapop Inspiron Mini 12. The screen size is apt and I think its not a bad buy.

What I am interested in finding out is that can the machine (which uses Intel Atom processor) run moderate duty applications. I mean I have several .net based apps which I would need to run and I hope these processors won't struggle.

I just need to double check to make sure that they support wireless internet.

Thank you,

Cheers,
