MBP 13" 2011 -- Docking Station Options
Sorry if this is long but I was having a very similar thought process and I thought it would be helpful to share my logic and course of actions:
I started to use my 2011 MBP 13" as my main computer and only used my desktop on occasion. I do use it all around the house and I wanted to simplify my life and reduce the amount of equipment I had running. If needed, I'm running Parallels for Windows but software can't duplicate my dual 24" LCDs.
As far as my data is concerned, I am using a Netgear NAS storage device so that all my computers in the house can access the data when needed.
When I am doing Web/Tech work, I would still like to sit down at times and have a full-size screen with mouse and keyboard. I was all set on the Idea of using Thunderbolt to simplify the docking situation so that I would only have one or two cables connected from my Laptop to the Monitor. The only option of course was to use the 27" Thunderbolt display for $1000. At CES, there were several companies discussing or showing off their own version of Thunderbolt displays. One could wait hoping that these displays would be a fractipn of the cost. There was another consideration -- the super high resolution of the 27" Apple Display but the question was; do I really need it?
Then it dawned of me ... If I am using an Apple Bluetooth Keyboard and Mouse, they connect directly to the laptop via wireless so the only two connections I would have when I docked was for the power and the monitor. That solved one big issue.
The second part of the issue: my needs don't really require having a built-in webcam in the monitor although there are many non-apple products that have those built-in as well if one wanted them.
These things taken under consideration, I am leaning towards purchasing a 27" ASUS LED Display with Display Port connection (they have one with webcam and one without) for around $300. It is 1080P. I don't need super-res. I like the fact that it also allows me to have other inputs (DVI, HDMI, etc.) For part-time use, $300 is much more comforting than $1000.
Finally, I have also seen products coming down the pipeline that will possibly allow one to use the thunderbolt to utilize an external Video Card (e.g. MSI GUS II). If this was the case, I would rather spend my money on this solution as it would allow me to enhance the graphics capabilities of my Laptop and do things (e.g. Video Games) that I don't really use my laptop for currently.
So I think the logic is ... the answer really depends on the desired use, future possibilities, and budget. For me, while I love the look and feel of the 27" Display -- I can't justify getting it to sit on my desk unused and with very limited capabilities for other things. I like the $300 ASUS option.
Hope this Helps!!!
