I'll just add my $0.02 here... I like this idea and maybe do this first while test riding a few bikes at the same time. After a few weeks of spin classes you can decide then if really want to invest in a "real bike" or not. It could be just a phase you are going through since your friend is encouraging you to get one too. After a few weeks of spinning, if you really don't like it then you just saved yourself a bunch of money.
But if you do like it then my vote would be to get a hybrid/flat bar type of bike. These are pretty comfortable and can go fast enough for most people who only want to ride occasionally on light trails. Look for a good used one to start and once you get hooked then you can sell that one a get yourself a bike of your dreams...
