Tax comment (2cents)... Remember, you're writing off the tax related to that expense not the dollar value as a whole for that expense. Uncle Sam doesn't see your $2,500 computer as $2,500. He sees it as a fraction of that based on your tax liability. Yes, do yourself a favor, keep record of all your business expenses. Do yourself another favor, don't go buying a bunch of stuff you don't really need in hopes you'll be able to write it all off. Not how it works. That's just debt. Debt to income ratio will affect much more in life than your taxation.
