My 550 Titanium is limited due to a drive (CD DVD reader)that does not function and a battery that is old and useless. I use it as a desktop computer with a few peripherals. I would love to get Tiger and have a faster computer and thought to cut corners I could possibly get a mini and have it attached to the the titanium thereby using the titanium for its keyborad and lcd. However feeble and cheap this might sound I was wondering if anybody could shed some light on whether it would even work...and if how?
