In terms of drawbacks, NeoPlanet's interface can feel a bit crowded at times, the mail client is rather rudimentary when compared to standalone clients as well as those included in Netscape and Internet Explorer, synchronization capabilities like those in Internet Explorer are sorely missing, and the browser lacks customization capabilities for the main toolbar and the links bar.
Overall though, while NeoPlanet isn't likely to present a threat to either Internet Explorer or Netscape's market share, it does serve as an attractive niche player for those just starting out on the 'net as well as for those seeking a browser with an alternative look and feel.
Pros: Customizable interface with downloadable schemes, IE foundation
Cons: Crowded interface, basic mail client, requires IE, lacks synchronization capabilities, no longer available for download — discontinued?
