Ok, here is my perspective.
1. I also only have 64GB. I don't use a lot of programs but tons of data. I store my data on TB HD's that are attached to the dock or to 64GB's USB drives. Also, whatever the amount, you can delete a lot of bloatware.
2. I've only had it 3 weeks but the build quality looks excellent. It matches ultrabook specs and is contained in unibody aluminum.
3.The only issue I had were the wifi/bluetooth issues discussed here. I replaced the wifi driver with the 221 version and I use generic bluetooth. I tested the wifi with my ipad and they are now both about the same. I doubt the wifi is as good as an external device or even a laptop but its now ok for my use. I have a 2 story house with a basement. The router is in the top level. I can receive the net in the basement, although I just tested it there. I use my W700 all over the main level without an issue. I assume future drivers will make it even better but even now its like other tablets - at least my ipad.
4. The size is the main issue - both for and against it. Its large compared to other tablets but small compared to other laptops. It can almost be considered a unique device. My main reason for getting it was the larger screen. The issue isn't whats better but how you use it. Its 11.6 inch 16:9 size makes it fantastic for horizontal use but poorer for portrait use. I mainly use it on my lap. Depending on the chair, I use it with the keyboard or the keyboard folded underneath. Although you can carry it in one hand, it would be uncomfortable to hold it too long with one hand. I wouldn't recommend using it on a bus, especially if you are standing. However, when sitting in my chair it runs all my legacy programs and new apps very well. When I first got it, it seemed bulky and unwieldy for a tablet. Howver, after the first day, I was comfortable with it and my ipad seemed small and boxy. Its how you intend to use it - not whats better.
5. I only use the bluetooth keyboard and occasionaly a mouse. Since I've changed the drivers they have worked fine.
6. I have got a maximum 8 hours but I agree with cylemmulo that 7 hours is reasonable for normal use.
7. I have had a few Acer machines over the years but I've never had a problem with the machines so I've never dealt with Acer support.
8. There is no right answer. I chose Acer W700. The build quality seemed similar. Acer was cheaper and had twice the battery life. Also, I wanted a larger screen as it suited my use. I am happy with my choice. YMMV.
