It is true that it was hard to figure out exactly what Sun was up to in their later years. They went on a massive buying spree of buying up smaller companies, including ones that couldn't possibly benefit them financially, such as StarOffice. The bought up Cobalt Server appliances, tried to sell their server appliances for a little while, and then just discontinued them. They bought up Virtual Box, which was another one of those "why?" moments. Virtual Box is useful for desktop virtualization, but it's not exactly enterprise level server virtualization type stuff.
Sun ended up going massively into debt by going on this buying spree, and the companies it was buying simply didn't seem to provide a lot of benefit to Sun's overall business strategy.
Their whole "open source" strategy was baffling from the beginning. It seems like they wanted the buzzword cred but had no clue how to make the process work.
at least they had one.
Virtualbox would have been an interesting buy if Sun had continued the bare metal project Innotek had going and expanded it.
Everything Sun did could have been interesting if they had any vision about where to go with it.
