With its clear display and fast processing, the TI-83 Plus incorporates graphing tools for mathematics and science course work, including statistics and finance. Incredibly useful for college boards--PSAT/NMSQT, SAT I, SAT II, Math, IC, and IIC--the TI-83 is essential equipment for advanced placement courses in chemistry, physics, and calculus.

The addition of the optional TI-Graph Link (software and cable) allows you to connect the calculator to your computer, permitting the transfer of files and data between machines. The TI-83 is powered by four AAA alkaline batteries and one lithium battery for backup, with an automatic shutoff to save energy. It also comes with a hard slide cover and is supported by a one-year limited warranty.--Barbara Price

Intelligent Detection Means Efficient, High-Quality Scans
The ScanSnap S1500 offers resolutions of up to 300 dpi--color or grayscale--without sacrificing speed. With the touch of a single button, you can scan up to 20 double-sided pages per minute.

You won't need to do a thing to ensure that your scans look their best, because the S1500 comes equipped with paper-feed detection to monitor page size, as well as color and black-and-white detection. Better still, the scanner automatically rotates, crops, or de-skews documents.

If a small document (such as a receipt or business card) is mixed in with a stack of larger documents, the ScanSnap S1500 can be set to automatically increase the resolution of the small document to help ensure that finer print is discernable. What's more, an interactive interface allows you to choose to easily and quickly bypass double-feeds such as taped-receipts on expense reports.

Four Software Packages Included for Document Organization and Protection
When it comes time to manage your digital files, use one of the four software packages included with the S1500. View, manage, and edit PDF and JPEG files using ScanSnap Organizer 4.0. Or, to do more than just view and print PDF versions of your documents, try Adobe Acrobat 9 Standard. This package allows you to create digital IDs and implement password protection to keep confidential documents safe.

To convert your paperwork into editable text, try ABBYY FineReader for ScanSnap 4.0 PC Edition. Alternatively, use CardMinder 4.0 to quickly scan business cards, extract the contact information, and place it into editable fields that can be exported to Excel, Outlook, and other contact managers.
