What exactly was the problem that you had with the text file?

2 things come to mind:

1) Did you have an office suite installed? some devices have one preinstalled others do not (if not download one from the market)

2) You sure it was a .txt and not a .eml attachment?

Android is based on Linux, you can even open up a terminal and do terminal commands...There is a lot of customization..you just have to get into the "Linux" mindset and not the "Windows" mindset..aka some things are different to accomplish different tasks.

ATM there is almost 0 customizations on WP7 as its a locked down platform like the iphone..it may change in the future..but thats what it is today.
