Generalizing here (and folks may disagree) but open source is almost always "not quite as robust" as commercial software.

And that makes sense--OEMs have more resources, more developers, and can tailor apps to their specific hardware.

(Just peek at OpenOffice vs. Excel--the "basics" work, but advanced functionality like PowerQuery available in Excel isn't to be found in OpenOffice).

Just my $0.02 though - YMMV

p.s. please don't view this to mean I'm not a fan of open source - I'm a huge supporter, and a Linux user -- but just offering an honest opinion.
