Alright, just read the incredibly in-depth (best review ever, wow) review from Anandtech. After switching back & forth on trying to decide to get the laptop dock or not at its ridiculous pricing, I ended up saying "fine, I'll get it & the phone bundle for the $500 + tax". Then, the tethering charge was realized. I really don't want to pay any more a month than I already do, being a poor college student (also a cheap one. hate spending too much money). Like I said, I've heard you can pay the first month's bill with the tethering added, and then tell them you want to take tethering off, and you can keep your laptop dock and still use it with wifi from your phone...but, again, not sure if this is true or not. Can anyone confirm yet?
However, now I've read this part of Anandtech's review about the docks, specifically the laptop dock, and I'm beginning to think, with my current situation of being quite low on funds, maybe I just shouldn't even bother with that particular dock. I'd really be wanting it for college classes (typing up notes quite often), and heavy (preferably HD) youtube usage. Both of which the Atrix 4G doesn't seem to have
quuuite enough juice to power the dock with, according to the review.

I quote:
"
Where the Firefox/PC experience breaks down is the minute you ask for more than a simple browsing experience. Typing in Google Docs is laggy. With a couple of browser tabs open I found that I could type three sentences before they'd appear in my document.
YouTube playback works, however anything above 360p begins to drop frames. While 480p is playable, anything higher is basically impossible to watch. Motorola preloads Flash 10.1.120.10 with hardware acceleration in its webtop Linux however there doesn't appear to be any way to force an update. You'll note that this is the same version of Flash that the Optimus 2X was running, although I'm not convinced that GPU acceleration is fully enabled under Motorola's webtop Linux. Monitoring CPU usage in Android shows that playing a YouTube video in webtop Linux eats up between 50 - 80% of the two ARM Cortex A9s. Hilariously enough, HTML5 video is unwatchable in Firefox on the Atrix 4G.
Light usage isn't bad, but open too many tabs and you quickly get a worse-than-netbook browsing experience on the Atrix 4G.
You can Alt+Tab to switch between windows when you're in webtop Linux however even bringing up the task switcher is incredibly laggy at times.
It's clear that the webtop app is Motorola's main reason for including 1GB of memory on the Atrix. The Android VM typically eats up around 40% of available memory, with Firefox another 16% during light usage. While Motorola could've gotten by with only 768MB, I believe the 1GB is probably perfect for the Atrix if you're going to be using it in webtop mode."
So, now I'm leaning more towards not bothering with the extra expense of the laptop dock...but I wish I had the financial freedom of not worrying about the extra expense and that I could just buy it right now like some of you have done! =)
So, as of now, I'm super undecided. Leaning towards the regular dock, vehicle dock, and the phone...only. And not adding any dumb tethering fee to my bills. :-\
