I am looking to purchase a new laptop for going back to college as my old laptop weighs about 15 lbs and is rather ancient. I am debating between a few. First let me say that I have never really been a mac guy but the Apple Air is one of my choices mostly due to price being less than the other two options. my other options are the Acer Aspire S7 and the ASUS Zenbook prime touch. The S7 seems to be similar to the air but in Windows form and I am slightly interested in the idea of a touch screen though I don't know how I would actually like that on a computer and not a tablet. Any insight as to which you think will be best in terms of performance or if you have other suggestions for laptops that will be both light weight and do the job. I should mention that I am going to school for marketing and advertising so most of what I will be using this for will be lecture notes and marketing projects such as story boards and such. Thanks for the intelligent comments.
