Well, to start I have issues that require me to exchange (dead pixels, light bleed, dust).. which could be ok, but in usage there are a few big things.
Browser lag is awful. For the power in the device it should be a smoother experience all around. Especially the typing lag when trying to reply to forums, etc. It's basically unusable.. well it's usable but leads to a lot of typos, even with the dock due to delay and missed strokes.
The Asus keyboard even introduces lag in things like polaris.
While not as bad as the browser lag, the entire device is just very sluggish to do anything.
Flash quality is desperately poor in all circumstances.. from what I gather, Asus did not include hardware decoding.. not sure why. Either way, it's not good. Most sites have html 5 versions of videos now, and those tend to look way better, on other devices.. but I'm guessing due to the embed tag used in given browsers, it's even difficult to get those to play in most cases.
App availability is just awful (It's early, I know) and due to browser issues (tried most of them, most of them fail in one way or another) falling back on apps is a must.
Even apps that have been optimized (USA Today for example) are very poor counterparts to their ios equivalents.. as far as UI goes... which also brings me to how there is a complete lack of unity on the devices.. even in the 'menu' icon position, changing from bottom to top..
The fact touch to click can't be disabled natively on the transformer dock trackpad is a disaster. It means one has to remember to turn off the trackpad with the hard button when typing anything in. At that point, why bother putting a trackpad there. In practice, the trackpad is bad. Additionally the buttons stick (which may be fixed wearing in).
I'm desperately trying to get out of the ios environment, but overall I just don't think android is there yet and this device, to me, should have probably seen delay to iron out quality and software issues.
It's disappointing that outside of mail, google didn't even bother updating their own apps for honeycomb... and also that anyone like myself looking to extricate from the apple ecosystem is greeted with such mediocrity. Before anyone takes that the wrong way, there are plenty of reasons I want to leave iOS, and apple has it's own plethora of issues.. however user interface and responsiveness are not two things on that list.
Sorry to be a party pooper.. I guess if I hadn't been using a tablet for the last 16 months, I wouldn't have the same expectations. I was hoping it would be 80% as good as the ipad as a tablet with the benefit of a netbook when needed.. unfortunately the speed issue is the largest deal killer. I can put up with limited apps, but not when I can't even effectively browse. Overall the device is slower than a dell mini 9 running windows 7 - which is slow.
One question it does lead to for me is.. do the phones perform better? There are certainly more phone apps available. However, the fact that many android handset users seem to think honeycomb is 'good' makes me wonder how bad gingerbread is and how sluggish the phones are.. otoh, it's had more revs...
I do think there is a certain amount of just 'being used to' a lack of polish it seems.
Btw, before I get crucified here, I am trying to be honest.. I'm a triplatform guy, and I couldn't care less who makes what or which os it runs.. so long as it fits my needs.
btw btw.. the typos in my first post were the result of trying to reply in honeycomb via web form...
