The posters referring to large display instruments as “entertainment centers” is the glider pilot equivalent of penis envy. While the SN-10b was state of the art for many years, technology has progressed. Large display glass is the present and future plain and simple. To call modern computers “entertainment centers” is frankly passive aggressive, you are insulting those that choose new technology over older technology. The new instruments are highly programmable to give too much information or just the required for each pilots’ desires on multiple pages including a photo of the turn point or airport if so desired. Also, the large format can be configured to be readable without reading glasses, which substantially reduces head down time. These computers, will show if you can clear high ground before your target airport, clearly show Flarm traffic, airspace, gives both voice and alarm alerts…. I highly recommend reading a manual to see what they can do.

If you want to stay with the SN-10b fine, I will not insult or belittle you for your choice, I expect the same courtesy.

By way of real world example let me illustrate a difference in the SN-10b to the newer larger format systems. I seem to recall a pilot in the 2014 nationals in Minden suffering a 1,000 point penalty for flying through restricted airspace. I am sure this pilot was well aware of how to operate his SN-10b. The new large format displays will warn you in both voice, alarm and display going red when you get within a pilot defined distance from such airspace. You would have to be brain dead not to understand and react to the larger format warning of airspace, or traffic.
The progression of change remains ever present, clocks that bind will be left to rust.

I get a chuckle when I see "extra" add on features offered for one of the most popular "entertainment centers" for $650 to $1650 a pop. Ninety percent of the offered up- grades are in the lowly obsolete SN-10.
