To access the object, you need to add the following using statement:

using Microsoft.SharePoint.Utilities;

I had a quick go through the SDK, an the following are what strikes me as some of the more useful functions this object provides (note, I havent used all of these yet, just went through the SDK then googled the functions I thought sounded interesting):

• SPUtility.FormatDate
  Allows you to format a given date to any of the SPDateFormat types

  DateTime curDate = DateTime.Now();
  DateTime regionDate = web.RegionalSettings.TimeZone.UTCToLocalTime(web.ParentWeb.RegionalSettings.TimeZone.LocalTimeToUTC(curDate));
  return Convert.ToDateTime(SPUtility.FormatDate(web, regionDate, SPDateFormat.ISO8601));

• Get the 14-Hive filesystem path
  Returns the filesystem path for the 14-Hive, or any of the folders beneath it.  This is typically (though not always) going to be C:\Program Files\Common Files\Microsoft Shared\web server extensions\12

  //Get path to features directory
  //Would typically return "C:\Program Files\Common Files\Microsoft Shared\web server extensions\14\TEMPLATE\FEATURES"
  string featurePath =SPUtility.GetGenericSetupPath("template\\features");

• Get Full (absolute) URL
  Converts a relative Url into an absolute Url

  //Get url to list item
  SPListItem item = spList.Items[1];
  string itemUrl = SPUtility.GetFullUrl(spSite, item.Url);

• Redirect to page
  Send a HTTP redirect to the client's browser

  //Redirect to specified page, adding querystring
  string url ="http://portal/TestResults/Pages/results.aspx";

  string queryString = "successflag=passed";
  SPUtility.Redirect(url, SPRedirectFlags.Default, Context, queryString);

• Send email
  Lets you send an email from the context of the given SPWeb

  //Send email from current SPWeb
  SPWeb web = SPContext.Current.Site.OpenWeb();
  string subject = "Email from the " + web.Title + " web";
  string body = "The body of the email";

  SPUtility.SendEmail(web, false, false,"someone@somewhere.com", subject, body);

• Transfer to SharePoint success/error page
  Allows you to transfer the browser to the ootb error and success pages

  //Transfer to Error Page
  SPUtility.TransferToErrorPage(ex.Message);

  //Transfer to success page, and specify url to move onto after "Ok" clicked
  SPUtility.TransferToSuccessPage("Operation was completed", @"/Docs/default.aspx", "", "");
