Lots of 'problem' threads here, so I just thought I'd switch it up and offer my ray of sunshine. I'm a user of the iMac/ iPad workflow, but recently enrolled in a supplemental ed class that required the use of photoshop on an laptop. Not wanting to spend much on a machine I'd only need for 3 months, I bought a mid 2010 Macbook Pro 15" with 8gb of ram and a 256g SSD for $350. Being a 5 year old laptop, the battery had over 1000 cycles and only held a charge for about an hour. Thanks to its SSD, it booted up in about 5 seconds. After putting the El Cap public beta on it, it boots up instantly and the battery lasts for almost 3 hours. Color me impressed.
