Depending on what you're using photoshop for (are you doing drawing or are you using it for other stuff) you might even consider an ipad like I got for my art. Can get a keyboard accessory for typing and shit. I very nearly went with a Microsoft Surface though, I waffled a looooooooooot and in the end chose ipad and don't regret it but Surface gave me a hard run for my money choice wise. This is only if you want this to double as a screen drawing tablet, since I saw you mention it. I also use it to watch movies in bed because that screen is gorgeoussssssssssss Otherwise I think these lads have you on a good track!
