Query: Garmin GPSmap 378 is a Discontinued Product

I purchased a Garmin GPSMAP 378 in June 2006 and paid about $1300 for the unit and some extra maps. Really liked the unit until I went to update it in Apr 2010. The only map updates available from Garmin are over two years old. Garmin will sell you this old update for $70.00. Garmin no longer supports this product and will no longer provide maps according to the Garmin tech rep I spoke to on the phone. Why would anyone want to purchase this product or any other top end (expensive)Garmin product that will be obselete within two years of the purchase date??
