Ok so i just got my new 13" MBA today, and besides having a LG screen (…) iam quiet happy with it BUT i have some questions first - after JUST browsing arround for 1h or so with the MB Air on my lab feel like it at least gets relativly warm. Why is that? I thought with the all the ssd stuff it doesnt get warm from souch easy tasks?

My other question is this - i noticed that webpages and stuff look relativly small. So i fired up my old macbook pro 13" and there it was. Safari (same version on air and mb) scales pages smaller on the air. I thought that i might have zoomed on the MB but i didnt (set both to cmd+0). Here are the pictures i took - you can clearly see what i mean (just look at the white space next to the content on the left and right)

what the hell is this? And WHY and how to make it look like on the MB
 
The 13" MBP has a 1280x800 screen.

The 13" Air has a 1440x900 screen.

That means that at the same font size (ex 12pt), words will be smaller on the Air than on the MBP. You can compensate for that by zooming in to web pages or by setting the font size in Safari's preferences:

Stetrain is spot on with the difference being the resolution.

The heat you're feeling is more than likely quite normal as well. Even though there's not a spinning hard drive to generate heat the rest of the components will still heat up even after a short amount of use. Chances are if you run the exact same stress test on a MacBook Air and a MacBook Pro you will see slightly warmer temperatures from the Pro, though I doubt it would be a significant difference. Apple's notebooks are designed in a way that the fan will push hot air out from the rear vent and use the aluminum surfaces to dissipate heat. That second part is important because they are really designed to be used on a hard flat surface (tabletop), as the gap provided under the aluminum bottom case will allow for air circulation to help cool the aluminum housing.

When using it on your lap, pillow, bed, couch, you are effectively removing that gap, which results in higher temperatures much quicker. The MacBook will more than likely still operate just fine but may be too hot for comfortable lap use.

This KB article explains it pretty well. http://support.apple.com/kb/HT1778
