I just received my Transformer from Newegg on Monday. I think it's a great tablet, but there are a few flaws or things that I like better on my iPad, the acer tablet or the xoom.
First is just a known issue with Honeycomb 3.1, the reply to an HTML email with any sort of apostrophe uses the XML code instead of HTML code to produce the apostrophe. It works fine if you're responding to plaintext emails or anything of that nature. But this is across the board for Honeycomb tablets running 3.1. There are a couple other Android quirks like Netflix and Marvel being stupid, but outside of that everything is at least on par to better than the other tablets available.
Specifically with the Asus tablet, I am going to have to return mine as mine had a manufacturing defect where the casing around the dock port is actually bent outward causing the casing to separate from the screen to a very small extent. Most people probably wouldn't even give it the time of day, but I'm one of those people where damnit I just bought this it needs to be perfect, if I dented it, that's another story, but if I've not touched it yet, then it needs to be fixed
Another issue I have specifically with the Asus tablet is my screen feels more grippy than say a Motorola Xoom or an iPad, your finger doesn't slide across the glass as well. Of course if I go with a screen protector this will all be negated, but just kind of odd that the feel of the glass would be different even between it and the Xoom.
The last one would probably be the port selection, not that it matters, but I think a microUSB port would be nice to have, again not a huge deal, I also like microHDMI better than the miniHDMI it has on it. I understand the need for the dock port since the keyboard is an option, but I always love the microUSB charging option
But lets put it this way, once I get my returned tablet back, it'll be replacing my iPad which will be eBay'd or sent to Gazelle. The no Netflix sucks, but... meh I can live without it.
