I'd disagree. It's the way large computer-related-industries work. That does not make it a good thing.
Valve buys Counterstrike. Games goes down the crapper, no updates for almost a year, no webpage updates. The dev team totally isolates from the community that they once socialized with. CS2 is okay, sure, but it's just a port from CS. And it doesn't even have all the models that CS had.
AOL buys Netscape. Netscape I liked because it was an alternate to MSIE, it was small, compact, and efficient. AOL buys it and all of a sudden it balloons out with dozens upon dozens of directories inside each other with no files and gibberish names, and at the very end is the directory your profile is stored in. No logic anymore. Code bloat up the wazoo. Bugs. YIM installed with it (EW! Get it off! Get it off!!).
There are other examples as well. Usually when this happens:
1) The big company gets money from the "good name" of the small company, because it's already tarnished its own name
2) The "good name" of the small company is ruined because
3) The big company totally and royally screws everything up and drags the small company down the drain with it.
Alienware probably should have stayed separate.
