I have the A6150. I bought it on Thursday. It is everything and more that I needed. It cost me £769.99 including a 19" TFT Emprex monitor. It is really fast, very quiet and stays cool even if left on for a long time. The only thing I've found is that the sound is a little tinny from the Emprex monitor but this is a minor gripe and can be easily fixed by buying a relatively inexpensive pair of speakers. I got Phillips (10w) speakers for only £29.99 and this has resolved the problem. I find it hard to say anything negative about it. Hope this helps.
