When it comes to technology and small businesses, not only are the devices you can buy nearly endless, but the technologies themselves that are available can be dizzying.

BusinessWeek offers up some small businesses technologies — ten, to be exact — that make the grade. Such as Google Applications:

 Tony started a biotech company this year and, wanting to keep the cost of technology down, uses Google’s (GOOG) free business word processor and spreadsheet applications. They do the job well. A client who’s in the recruitment business needed a quick way to search thousands of résumés on file. So he downloaded Google’s desktop search and solved the problem—for free. I have other clients who use Google’s calendar, e-mail, and analytics. This stuff works. And did I mention it’s free? Hang on. Maybe this Web 2.0 stuff isn’t so bad after all.

Other technologies listed include  remote desktop technology, desktop sharing software, free conference calling, wireless connectivity, e-mail marketing services, contact management software, hosted phone systems, messaging software and SQL server.
