Well I just registered on the forums JUST to reply to this topic that i saw while browsing reading about the CQ50.
Recently, I ordered a cq50 off the HP website, and because i live in the states i cant give a number in the currency you guys are saying, but for me it was about 430$ without tax.
Though I havn't received it yet, i believe the CQ50 will outperform the 1525.
You stated that the 1525's processor will be better for you, it really depends on the tasks you will be doing. Because of the way AMD's processors are, they are faster for things such as gaming. With intel, this is the same with things like video encoding.
Even though there is a difference, it isn't exactly a HUGE difference to where you should struggle to decide between the two.
The CQ50 has a better gpu, the 8200m is much better than the x3100 even though neither are amazing.
Also, I wouldn't worry about ram because 3 gigs is more than enough to run photoshop and all of the programs you are stating.
Personally, I'm going to dual boot myself windows xp for better performance, as I dislike vista.
I actually had to choose between the two also, and i decided to order the compaq because overall, I would rather have it built by hp than dell, and it had higher specs, for a cheaper price.
Also, I wouldn't worry about the amount of time it lasts, because if you are able to keep it clean, and treat it right, it should last you a while.
When i get mine in, I can tell you what i think about it and how good it actually runs Counter-Strike: Source which is mainly what i play.
I hope i was of some help, and will check up on this topic now and then.
Peace
