So I have gotten in to some JD GPS equipment in the last 3 years.  Started with A new 3000 reciever and a used 1800 dispay for row finder/parallel tracking when spraying.  Added autotrac when I upgraded the planter/sprayer  tractor that came with an intergraded valve.  Added a 2nd system for tillage this year and put swath contol for the sprayer on the older unit - really liked it, saved some time and money.  Even tough I have spent alot of $$$ for what I have, I am pleased with the results. So when are the big manufacturers going to let us just buy an I Pad or something similar and load the programs and activation to it?  A new 2630 with no activations is $5 or $6 grand?  Thats alot for a touch screen monitor and a faster processer?  Most of the software is in the controllers or an unlock you pay extra for.  I like the used 1800 displays I have, would like to have touch screens, but not at the price needed to upgrade.  They must be making money hand over fist on this stuff.  Even my $80 garmin gps in the car has a touch screen.
