No one incapable of reading the NA27 apparatus criticus should be bothering to read a Greek New Testament in the first place.
For actual study purposes, I would carefully agree. But I only just got into the aparatus myself a year ago, and I've been reading the GNT for two years prior to that. While my reading the last year has been more fruitful (I've found places I disagree with NA27), even just being able to read the GNT with the variants the editors have chosen has been absolutely invaluable. If not for actual word-for-word study purposes, then it is certainly true for at least better clarity.
The illustration I always use is this: reading the Bible in Greek is like watching a 52" high-def flat screen TV vs. a 9" black and white. Same picture, but MUCH better clarity.
I agree totally. I find that Metzger's commentary is invaluable. I bought NA27 and Metzger together, because I didn't see the point of NA27 without Metzger.
Again, for a very detailed, analytical study (i.e., preparing papers and such), I absolutely agree. Heck, I keep Wallace and Baur beside me as well, and my TNDT is on the shelf on the other side of the room :p
If you're a Libronix user like myself, then you would have been amazed and disappointed that the NA27 which comes standard in such packages as the Silver Scholar's Library (which I have), doesn't contain the apparatus criticus. You have to purchase the Stuttgart Electronic Study Bible to obtain the apparatus, which is very annoying since out of the entire work I would only use NA27, the morphologically tagged Septuaginta, the CCAT LXX database, and the Hebrew/Aramaic-English Lexicon of the Old Testament (though I'm saving for the HALOT/BDAG bundle). Incredibly, after all that I still have to purchase Metzger separately. I wrote to Logos objecting to this annoying packaging of their products, but never received a reply.
I just went through the new sales pitch for Libronix, and I must say I'm very impressed, especially with the new search features. The new diagramming module is absolutely amazing. I'm going to examine Accordance and BibleWorks before I make a decision on which to purchase, though. My problem with all of them is that for the money they ask you to pay, no one is really providing a complete library. Lot's of great stuff in all of them, but they are all missing something
As for the issue you brought up, it so happens my Greek prof is a Libronix user, and the Libronix development people said that if sees a need in the program, then to send them an email and they would see what they could do to get it added to the program. I will definitely bring this up, because he would like to use the program to teach TC. Maybe they'll get it in there . . .
