Others wants to have it bigger.
I don´t have any problem with the size as I generally don´t keep something like this in my trouser pocket. It´s good to be operated without the need of a touch pen and the size is still big enough to read without the need of a magnifying device or permanent resizing. If I wanted to have something smaller I would miss the practical use of any “smart” feature. I then would rather fallback to get a “dumbphone” just for phoning. I also judge this from the technical point of view to something called limit calculation in relation to design (how small can or should something be designed to still be properly (comfortable) operated.
Before my purchase of the FP2 I checked the size measurements and found it to be good for my needs. Also there was a foldable template available for download and print for those in need of such.
Reading through this forum I found posts of users not being quite comfortable with the size. I believe most users other than me did own handsets before the FP2, so before their purchase based on their experience they should know if the size would suit their expectations or not.
I am used to know what I am spending my money on, specifically such a hunk of more than 500€. But buying something like the FP2 and finding out after unboxing it that the size is not matching the personal expectations, somehow looks to me like (rich) people often keep it, not thoughtfully spending their money. Here is a solution though - simply buy the next phone of whatever type, maybe there´s more luck this time.
As it seems longevity and fairer conditions cannot overcome such simple expectations which in a matter of time drive users again to replace their FP2.
(One person here sold its FP2 specifically mentioning it being too big as one main reason)
I would hire the one not having the phone quickly at hand as this person may be able to concentrate on its (non-mobile phone related) job, for which it´s employed and paid for.
If there wasn´t the price which would rather rely on technical specs than only on size.
