Reasons why:
1. Flash
HTML5
2. Java support
What do you need it for? Explain.
3. Widgets
Can't argue with that, even if I don't use them
4. Music Beta
Doesn't work with linux, still requires invite
5. Unlocked Bootloader
Why does this matter?
6. Tegra 2 Gaming
"Don't make me laugh" ~Shao Kahn... Watch a video of SF4 on iOS and then tell me T2 Gaming can compete with even last years iPad...
7. Android 3.1 with USB support
iOS 4.3.3 with iTunes support
8. Better G Apps
What does that mean?
9. Better Camera
For pictures? yes. For video or video calling. No
10. Correct aspect ratio to watch movies
You lose real estate for that aspect ratio. I for one hate having a narrow strip of a website. It sucks panning back and forth.
11. Chrome browser
Safari?
12. Google Books
iBooks?
13. Updated Multitasking to support 15 tasks...I think
Multitasking?
14. Unlike the Ipad, I don't pay for my apps
iTunes has free apps too...
15. Better productivity (with docs 2 go, or GDocs)
I'm starting to suspect you have actually never held an iPad
16. Better speakers
Depends, but I can't really argue this one..
17. Cheaper than equivalent Ipad
It's $599... How is it cheaper than $599?
18. SD card slot (when it's supported)
That is hilarious
This is why the iPad is a better purchase than the Xoom;
The iPad 2 will be supported for atleast 2 years with updates!!! and iOS will probably have more Tablet-friendly apps until long after the Xoom is EOL...
