Keeping track of depreciation for a small business is a hassle but once you get it setup it doesn't look to hard to maintain and track.
Nice explanation of tracking depreciation using Gnucash here:

and here:

Probably easiest to use a tax program like TurboTax to compute your annual deprecation on your assets and then update Gnucash. That way you can generate accurate financial statements and it's all tracked in one program.
