flynowpaylater is right:
surely this is a one trick pony; the pony looks cute, and it does the trick just as you expect. The issue we all should debate is whether there are enough clients who are completely satisfied with that one trick.
The lesson from the industry over the longer term is that clients upgrade, migrate, and soon tire of one model. They want to go further, faster, longer, and one wonders whether Blink & co can keep enough of their clients satisfied long enough to reach breakeven (whenever that may be...!) before they tire of it.
If clients were satisfied by a one trick pony, wouldn't NetJets Europe be offering a one-type fleet today? Skyjet/VistaJet, AP, most operators, and all brokers offer clients choice across the range. In the end we all aspire to upgrade our cars, houses, class of travel, whatever, so how long before a new Mustang user today sees a CJ2 and dreams of all that space, then finds out that the price premium is negligible?
And won't the crew do the same...?
