Have just installed 2.0 and try to get into it. Have no experience with earlier versions so I am a newcommer.
I use Croome brower and Joomla 1.5
The display of choose numbers of articles is not nice.

Looks like you have a large product image causing the other elements to be squashed.
You can restyle the layout to suit your preferences by editing the views and using template overrides.

I usually recommend the use of Firebug on Firefox to aid style editing, but there is a version of Firebug (http://getfirebug.com/releases/lite/chrome/) that can be installed in Chrome and used with Chrome Developer Tools provides a useful tool.
