I think the new Elise will be just fine as my daily!
This raises a really valid point: The suitability of a particular car for your mundane use is as much about your expectations
as is it about the car.
As I posted in another thread, if you've daily driven any factory high performance car of the 1960s, you have experienced a less polished vehicle than a Lotus built in this century. The only way in which an Elige is deficient relative to the assortment of 1960s sports and muscle cars I've dealt with over the decades is cargo capacity.
Another piece of expectations would have to be your environment. If you live in SoCal - what a shock, you can DD a Lotus 12 months out of the year pretty easily. Ditto most of Florida. If you live in the rust belt, it's a greater (and in my opinion rather unwise) commitment to not have a winter beater.
Here in the Virginia piedmont, I park mine when there's salt on the road - typically 2-3 months starting in late December, and ending with the first heavy spring rain in early March. So I don't have to DD in snow. My car is garaged and I have covered parking at work, so I don't have to worry about how well the defroster copes with snow, for instance.
I drove mine to work yesterday and today, and am planning on doing it for most of the summer and fall - particularly because I'll be putting a new convertible top on the Celica.
