1-Naturally Joomla 1.5.x as the successor of Joomla 1.0.x has much more features and capabilities. A few of these capabilities are:
a.Enhanced core features
b.Nicer look
c.More SEO Friendly (Search Engine Optimization)
d.More Flexibility on the template design
e.Improved Admin Panel

2-Joomla 1.5.x (or simply 1.5) is in the center of attention of Joomla.org. According to Joomla.org developing and updating Joomla 1.0 will be discontinued soon and as the result:
a.There will be no new updates which may cause Security Risks
b.There will be no new components based on Joomla 1.0

As you realize if your website is based on Joomla 1.0 sooner or later you should migrate to Joomla 1.5.

Leave the work to Realtyna Joomla Experts
Upgrading/Migrating Joomla 1.0.x to 1.5.x is a very complicated task and requires a Joomla expert to take care of it in order to avoid disasters. The reason is that almost all parts of Joomla must be upgraded one-by-one due to compatibility issues, like:
a.Templates
b.Components and modules and plug-ins
c.Database Format
d.Transferring contents
The upgrading cost defers based on the complexity and volume of the website. Realtyna service cost starts from standard price of USD 199 for normal websites with 30-50 pages, up to USD 599 for more complicated situations. Along with any Upgrade 1.0 to 1.5 order, Realtyna issues a Magic Updater Complimentary License (value USD29). With Magic Updater you can update your Joomla from 1.5.x to any higher version with One Click!
