Mine doesn't. Mine even opens in Small Mode. These are configurable settings. If you dislike how they are set, reconfigure them. Have you also not disabled the News Window that pops up on startup? You can turn that off, you know!

Okay? Do you spend substantially more time using the Steam client to browse the Steam storefront than to play video games? Seriously?
On top of that, will five seconds of additional load time cause you to change your mind about making a purchase? If so, you really weren't interested in the either the thing you were buying or the search for that thing, and it's -very seriously- definitely for the best that you were dissuaded. Valve is making money hand over fist, so the lost sale doesn't matter to them and you get to use that money on something that you're not -at best- aggressively tepid about.
