Actually, really depends on individual; For people "already" looking/make up their mind at DSLR, they won't complain about the size and bulky as they already know it (but it doesn't mean that later they won't change their mind, it depends if they truly knows what they want and what they're getting, e.g. not just thinking of getting a DSLR for the sole reason that it can produce better pictures, without understanding what they actually needed to do and know).

There're people who just want a good camera which can take good pictures in lowlight as they struggles this with their compacts or phone camera; If there is a choice, they would of course, prefer something that is smaller than DSLR, easy to keep, easy to use, etc. But, they might think only DSLR can do the job, and most people will also tell them, get a DSLR, without telling them the details, or they see some people took some great photos with DSLR, so they think, if I get one, I can also take great photos like them.
After they get, they may face problems:
1. Optical Viewfinder, seeing through the viewfinder gives a different feel, etc. Plus, it's unlike the LCD, where you can see the "effects" changes, and several differences. Sure, they may think it look more coool and professional at first, but later, they will get bored of it.
When using the LCD (LiveView), the black-out and slow performance, will be kind of annoying for usual point and shoot. users
2. Difference in usage, not as easy to use as point and shoot, shooting with compacts is actually far easier to hold, carry, compose, reach, etc.
3. More maintenance and care, sensor cleaning, dust, fungus; Try tell them these, and the cost to maintain/clean. Most people don't tell these things.
4. More usage issue, e.g. VR, wait for VR to kick in, DOF issue which they don't really face or even know what is it with Point and Shoot. Sure narrow DOF is nice, but when they want to take group photo or macro or landscape, suddenly they find it's not easy to get the focus they can get with point and shoot; Or probability of facing with front/back focus issue.
5. For people who want to bring camera to almost everywhere they go, they will slowly find DSLR not really suitable for them unless they LOVE carrying bags around, but usually, for formal dinners, etc. I don't think much people will want to carry something big around. Sure, when the thing is NEW, they carry it around, but as the feelings fade, things will start to change.

My point is simple: It really depends on what the person is looking for. If the person is really looking for a DSLR and want a DSLR, it'll be different, but there're actually many people, who just want a good camera, and that doesn't necessarily be DSLR; DSLR may suit them if they know and understand the drawbacks of it, but it's usually may not suit many people. Many people after they got it, later only they realize or understand (some people can't understand from words or when people tell them, they need to experience it), and later would get something smaller/more compact and keep the DSLR for special purpose (which may actually never/hardly use at all; It's quite disappointing to see this, especially if it's your friend).
