When comparing what hardware, Blackberry versus Treo versus any other type the specs can help you see clearly. They pinpoint noticeable differences that one would want to be aware of before purchasing. The decision rendered over the copyright difficulties by the courts makes the Blackberry system no less appealing. Yet if it were a product that might lose support, over a product where the question has never come up, Treo would have an advantage.

Blackberry has a large ring of support because of its keyboard which is based upon the one people are used to. It is relatively easy to use as well. Treo is new to the market and therefore the model 650 Smartphone may not register with users. Blackberry has many units available, and has been in the market for years. The development of a copyright issue concerning its technology leaves it subject to not being available. Treo is very similar in its looks and functionality to Blackberry.

Treo as a $299 [model 650 not with Windows mobile] purchase is a well-priced unit. Associates who use Treo such as PALM technology [click] in both the 650 and 700w versions, has the appreciable advantage in the 700w of Windows mobile technology. The issue with meaning for this technology isn't just reaching ability (The cellular carrier difficulty will exist until the satellite problems are overcome) rather the problem here is ease of use, and capacity.

The less pricey 650 units come with the following software:
Audible Player
Blazer(r) web browser, Camera, (photos & video), Calculator, Calendar, Camcorder
Camera,Contacts,DataViz(r) Docs To Go 7,Handmark Pocket Express,(trial version)

Memos,Messaging,Palm(r) Desktop - PC & Mac,Palm(r) eReader,Phone,RealPlayer
Tasks,VersaMail(r) email client,World Clock,Zap! 2016, link to Microsoft Outlook (Windows only)
The slightly higher priced 700w has a few more buzzers and whistles with the following software package: Software on device: Bubble Breaker,Calculator,Camera (photos & video),Downloads (Verizon),File Explorer,Internet Explorer Mobile
Microsoft(r) Office Mobile,- Word Mobile(tm),- Excel(r) Mobile,- PowerPoint(r) Mobile

As you have discovered the difference in the two units is largely going to be in the function of capacity. The 650 has 32 Meg memory, the 700w has 128 Meg memory. Given the comparatively minor software differences, for the additional storage it is quite possible that the 700w is priced right for the difference.
