[Asus  Eee Pad Transformer Prime] nurrwick:
I just went whole-hog from an 11" MacBook Air to the prime plus dock in preparation for beginning graduate school later this month. Thoughts:

You notice the added weight because of the smaller physical size. That's *notice* not *suffer from*.

I plan on writing and reading with it. It has any one of a number of ways to write or take notes, and the kindle and google books apps are both loaded and ready. I have yet to see how many of my textbooks I can get through those options; either way, I'm pretty well covered, I think.

The complete lack of Java (not javascript, Java itself) in a browser is a downfall. I am going to deal with this by using RDP and my work computer, which is a windows machine, because it presents a better security system from out in the field. Splashtop is not encrypted at all, which probably means it'll run faster if I connect to my Mac while I'm at home, but I wouldn't expect it to be a good solution over two VPN connections (work computer to work server, work server to prime). Other browser-related issues come up every now and then, some of which you can get around by using the native browser's "request desktop site" option, but I had to go through native, firefox, dolphinHD, and finally Opera before I found a browser that would work with my university's trouble ticket system. That's almost 100% likely to be the university's fault for implementing a bad system, but whatever... I can't change that.

I am getting used to switching apps the android way and copy/paste in ice cream sandwich. It really isn't taking very long at all. Once I exchange my dock for one that's not bent, I think I'll be really happy with the point and click interface asus has come up with. I tried the gesture mode and it wasn't very intuitive, but I didn't try it for very long. I will say the only thing I really miss about pointing and gesturing is that I got used to the gestures for forward and back and expect them to work for everything on the tablet. Most of what I did with the MBA was web-based, so using forward/back gestures made a lot of sense. Now they're gone and I'm struggling a little to remember to use the keys.

Battery life is definitely a hell of a lot better than the Air. Mine had something like 140 battery cycles on it and was down to about 4 hours max, give or take, at minimum brightness. I definitely can get two nights of internet out of just the tablet itself, but with the keyboard dock, I think a whole day of library research isn't out of the question. The one thing I don't like is the length of the charger cabling and the seemingly frail construction of the sync plug.

I was initially worried about the sound output from the prime versus what I had in the MBA, and I can tell you the volume level I get is more than enough for what I watch, especially considering you can hold the tablet a lot closer to your head. The only problem I have is that if you rest it against stuff in horizontal mode, either your blanket and sheets will muffle the speaker a little bit or the power button will be pressed every once in a while. Minor problems, really.

I'm happy so far, just under a week into owning it!
