In my opinion, it's like shoes. Those that fit me beautifully, aren't necessarily going to fit you at all.
So, Dolby Speakers - On stereo this make no practical difference (I have a 7.1 THX system if I want good sound).
Higher Res camera - Doesn't necessarily mean it's any better. (Anyway, they're all equally bad compared to my 39Mpixel digital back, or even the dSLR.)
DDR memory rating - I personally wouldn't get hung up on how fast the memory is, unless I had definitive information on the rest of the elements involved in the data flow is equally fast. (ie my Mac Pro is faster than lots of other computers with the same speed processor since on the Mac Pro the data can be shifted around real quick)
More ports on the tablet - running the battery down faster! I guess you have to have those ports on the tablet since you don't have a keyboard dock!
'The additional keyboard just turns it into a netbook' Bingo! it can ALSO be a netbook, with all the ports, extra battery etc, but you don't have to have it as a netbook.
I wasn't going to buy a tablet - they can't do anything I can't already do better on something else I already have... but then Asus brings out the Transformer ...Grrr!
Anyway, that's my considered reasons both for buying one, and also response to what you posted. Please don't take offence at anything if it seems out of place. It's not meant to be. Enjoy whichever you finally choose.

+1 to this...well said. I have to say, if I was choosing between better sound on a tablet, or a better screen, I would choose the better screen. I too have surround sound, but I also have an led tv so let's face it, I'm not buying this to get a theater-like experience. As for the bleeding screens, that is only a percentage of them (see the forum, there is a dedicated thread for that issue).
Personally, I didn't see much of a reason to buy a tablet either, until I realized that with the TF, I am getting a netbook as well (which I would use for composing emails and typing on forums

. The tablet function of the TF would just be a bonus for light browsing around the house and mobile entertainment (plane/car rides during travel).
As for the idea that one feels cheaper than the other, that is a matter of opinion. Look at the iphone for instance (hardware and os). Some people feel they are classy phones, and others feel like it is fit for a child with the simplistic user interface. Not only that, but I certainly consider the weight of a device that I may be holding for hours at a time, so "plasticy" is not always a bad thing. I'm not trying to impress anyone with this, I'm buying for the functionality.
OP, the fact of the matter is this: Everyone will prioritize the features of a device differently, which is why there are choices in the market. It sounds like you have your reasons and they seem well thought out from your perspective. I have seen many on this forum, and others, that choose the Acer hands down so you are not the only one

. If you are happy with the Acer, I would not stress over what COULD BE with the TF. After all, think about how mad you would be if you trade up for the TF and your initial feelings in the matter were only confirmed. That would suck lol. Hope this helps with your decision....though I believe the decision has already been made
