I've had my MacBook Pro since early 2008 and it has proved to be a great uncomplying hero as I've traveled all over the world with it, but recently it has taken a longer to boot up and there have been the occasional freezes. This was confirmed by a quick check with Disk Utility. Whilst I keep regular backs ups of key data I decided to do a full backup of the entire disc and I got in touch with Mac:Upgrades.
Those guys were extremely helpful in going through the various options, in the end I replaced the hard drive with SSD, replaced the optical dive (which I can't remember ever using) with a new larger hard drive and upgraded the RAM. I dropped the machine off late afternoon and picked up the next day and it was like getting a new machine! Without doubt this has been the best value upgrade ever.
