It's obvious to anyone watching the google has absolutely destroyed iOS in terms of usability, fluidity, function, and UI. The widgets and notifications, and general continuity of the UI experience is exceptional, and will REALLY make it a great tablet OS (unlike iOS which is a blown up phone OS).
The problem is that the android market is a ways off of matching the app store, and so even though honeycomb is unspeakably better than iOS, I would still choose the iPad until the android market catches up. Even the good apps on the android market are usually just ports from iOS, which run much worse than they do on apple hardware (that they were originally designed for).
Having all of those amazing widgets and notifications will make the honeycomb tablet experience MUCH better than the iOS iPad experience, BUT in the end it comes down to what apps you are running, and until the market can match the app store the iPad will still win.
Seriously just think about it. OK let me open 12 difference applications in sequences on my iPad to accomplish what I can do with honeycomb by glancing at 1 or 2 of my home screens (full notifications, weather, calendar, facebook, twitter, news, email, bookmarks, all on the home screen ready RIGHT away). With iPad you click the home button, click on the apps folder, click on the app, wait for it to load, look at the info you want (say it's facebook), press the home button, click the app folder, click on the app you want (lets say weather this time), look at it, press the home button, etc... Do that 12 times and it's officially taken you TWELVE TIMES as long to gather simple information and updates, that are given to you all together and unified with honeycomb. That is why iOS completely 100% looses, and the only thing saving it is the pretty design of the hardware, the phenomenal support from apple, and the robust and polished apps/app store.
If you disagree, i'm very sorry to say, you are a fan boy plain and simple. I know people don't like this term, but in a case so obvious as this, there is nothing else to say. I've already stated that due to the app store, the iPad still wins overall, so i'm not saying that googles fancy UI makes it OVERALL the winner. If apple actually updates iOS to include proper notifications and widgets (maybe like a mission control thing from Lion) they can easily propel ahead of honeycomb due to their superior apps/apps store. It's just a matter of Apple stopping with their typical mantra of 'just good enough to get people to buy it', and actually try and pull ahead.
