In an ever-expanding fight to keep your eyes on the road where they belong instead of on your mobile device, the iPhone app Text'nDrive has been made available at the App Store. The free version, which has been specifically tested with Gmail, AOL, Hotmail, and MobileMe, will read up to the first 45 words of an email to you. For $20 USD you can get the full version that pumps the word limit up to 500 and even allows you to dictate a reply.
According to CEO Daniel Robichaud, Text'nDrive is an "innovative solution which we hope will entice more responsible driving habits and ultimately make the roads safer for everyone." SMS functionality is reported to be under development, and the company is actively taking user feedback to improve the product. Text N'Drive is also available for Blackberry and is "coming soon" to Android.
