Sounds pretty boring / mundane and (understandably) blinkered based around evolutions of things we have today.
But, touching on the boring stuff:
-12-16GB RAM on average sounds incredibly low, for a primary computing device. System memory has increased by approx. 16-32 times since Y2K. Admittedly, there will probably(?) start to be diminishing returns so there will less demand for the same rate of increase.
-Likewise I'm not sure that a primary home system (lets assume we include network storage or whatever) would be only 5-10TB in 2025, even allowing for cloud storage probably people will have high definition video they've recorded, cache for streamed stuff etc. I suppose it all depends a bit on what alternative storage solutions are available come 2025, so you may be right.
-All laptops having SSD seems quite presumptuous that the technology won't have been superseded by something new; again, because I'm blinkered by current technology and limitations I can't think of what might replace it, but it wouldn't surprise me.
Anyway, my vision isn't so much that we'll be plugging smartphones into traditional peripherals, more that we'll have a much smaller device (say a watch) that can either universally connect to devices wherever we go, or have a backup(?) holographic display (perhaps 2025 is too soon for this), possibly a headset/glasses you wear. There will be some 'new' form of input whether that be voice commands, based on eye movements etc.
