I own this tablet, and I'd have to disagree.
I've never know it to be slow. Seems zippy enough for everything I do.
It has access to the full Android market (many Android tables don't)
It has apps for everything I need to do (including apps I can't get for my Iphone 4)
I can directly access my home network to pull/push files - can't seem to do this with my Iphone.
I can read/edit documents/spreadsheets, etc. I can print to my network printer.
I have a combined calendar showing google calendar and tasks, so I can use this as my day planner and to-do list.
I can watch movies from streaming from my DLNA server
I can watch movies from Netflix
I can watch TV from my HAVA.
I can use Skype to video conference.
I can use VNC to remote control my desktop computer.
I use it for turn by turn GPS navigation
I can do all of this with free apps in the Android market, and I didn't have to root it or do any complicated tinkering.
Some of these things can be done with an Ipad, but there are some (calendar widget, combined tasks and calendar, etc.) that I haven't found for my Iphone 4. Google maps navigation is also much better than anything I found on my Iphone for free as well.
I'm not going to get in to whether this is better than an Ipad or not, as I've never owned an Ipad. My point is, I'm pretty demanding, and all in all, I've been very happy with it.
