27" may seem large but its really not. An analogy would be people watching TV on 20" or 27" years ago and now on 46" 50" or 60". Its all about getting used to it. As for the SSD, this is the tech of the forthcoming Macs & PCs. At this point it seems like no machine can fully take advantage of an SSD's capabilities and the price is not releastic for the benefits derived.
True but on average, your going to be sitting closer to a computer than a TV.
Big screen TVs "work" due to you being 6 feet or so back.
I'm not knocking the 27" as that's what I'll be getting (part of the big screen TV mentality imbedded in me) but I could see the size coupled with closeness making it harder to see or take in everything on the screen (thinking for gaming especially".
I remember going from 14" to 17" for my gaming laptop and it made a difference (negatively), at least while getting adjusted.
