Access 2000 vs Access 2010

[JHB]

Hi:

I have a number of significant applications written using Access 2000.
I am thinking of moving up to Access 2010 because I have to develop
apps for the internet and I am told that 2010 is a good and easy tool
to develop Web based RdB applications.

I have 2 questions:

1. Is it really easy to develop web based applications with Access
2010. Easy in this case means as easy as it is to develop applications
in Access 2000. If it is not, can someone point me in the direction
of better software (which allows easy development) for RdB web based
applications?

2.Will current Access 2000 applications run under Access 2010 or is
there a big conversion hassle?

Thanks in advance
