I'm on the other end, I would rather see the lines not get darker in the comfort o my bathroom and know the pg isn't viable then hear it via beta numbers on the phone in my office. Having the nurse tell you they haven't doubled - the hard cold scientific factual number, is so much harder to hear when you don't expect it. Being prepared for the number not to be great makes it a softer blow. Beta He!! is horrid. At least with BF-WTF's there's still some semblance of a thread to hang on to.
It all pretty much sucks though... I'm not sure any of it is easier to deal with than the other.
I like the digi idea. Unfortunately once you venture into the realm of progesterone or other medications during the 2ww (or ones need with a BFP), your hands are a bit tied in regards to testing. That's the position I'm in at least.
