New convert here - liked my 13 inch MBP so much that I went out and got a mini as well. OK - after I got the mini I put 4gb of RAM in and also a 500GB 7200RPM seagate drive. Well now I am considering putting in a 80GB X25 SSD to run OSX and Windows 7 and use the 500GB for applications etc. The 500GB would be hooked up via an external enclosure and usb powered. Is there anything I would need to be aware of running my apps and data off an external drive? I think it would be speedy with the X25 - but the price was steep so I am considering returning it - what are your thoughts. This is the family machine - photos, banking, email, surfing etc.
