I bought the base 2010 15" MBP 2.4 i5 last month from Amazon for $1,675 no tax and free shipping. I just doubled the RAM and am using all 8Gb for Photoshop CS5. Next I will likely get a Hitachi 500gb 7200 rpm drive for about $69 (I don't care if it takes 4 seconds longer to launch an application so not in the market for an SSD besides I prefer the storage space and performance is already great. For $200 more I could have gotten a 5% faster laptop but instead that $200 gets invested in more ram and bigger and faster hard drive. Already sold my old ram for $40 and will use my 320gb stock drive as a cloned backup.
Very happy and would do it again. As long as it does everything I need fast I don't believe in future proofing since the extra money spend up front is best used to upgrade more frequently since prices drop fast. Next year Light peak and Sandy Bridge, year after that big and affordable SSD drives, then IPS panels... I would rather spend less upfront and upgrade every two years than three, but if you need more power today then just get it
