On my machine, Microsoft Word 2007 takes about 16 megabytes of physical memory (44 of virtual). Its startup time is just under one second. I have loaded some third party addons, which no doubt contribute to that negatively.
Also, this version is noticeably more bloated than the old ones. In particular, 2002 (included with Office XP) was an incredible speed demon, with typical startup times of under a half second in the machine I had back then.
