I'm sorry but that is just not true.
Subjective appreciation can imply you like the aesthetics of the thing.
You can objectively appreciate it however, the display has a size and a resolution, the thing has a weight, it has specific capabilities (CPU, battery, gpu, memory, storage, OS, apps) - it's not a piece of modern art but a technical gadget.
No Peter, I do not imply that I "like the aesthetics of the thing", neither do I "think it's it's a piece of modern art" - that is hilarious to imply that. Where I agree with Synaesthesia, is that:
Not everybody likes the same thing (it is subjective, thank goodness). You happen to like Dell monitors, it does not mean that everybody will like Dell monitors - no matter how good the monitor might be. It is purely a personal preference, that goes deeper than just the form factor.
When Apple announced the iPad in January, I doubted wether I would find a niche that could justify purchasing it. I went ahead and bought one anyway, based on personal experience of never having been let down by Apple hardware in the past. Three months later, and I can tell you that I am very happy that I made the purchase - I do indeed, make regular use of it, and it has therefore created it's own niche in my daily life. Yes, I am disappointed that Apple did not include a camera (they were quite capable of including one), however I am still very happy with my purchase.
However, having said the above, I am not naive in thinking that because I find the iPad an excellent purchase - I do not think that you, or anyone else would feel the same way. We are all different, and have different requirements. Likewise, if you don't happen to like it, it does not mean that it is a useless device - perhaps for you it is - this is where the subjective appreciation comment applies.
