I've got an early 2008 MBP (2.5GHz C2D/4GB RAM and 7200rpm internal HD), which is getting a bit on the slow/unresponsive side, particularly after upgrading to Lion (Finder/Mail/iCal particularly have lost their snappiness, with random pauses when doing just simple tasks), so it may be time for an upgrade to an iMac, as I've just got a MacBook Air for portability. Would you mind giving me your thoughts on the following; I know it's just speculation, but advice from people's experience would be appreciated, to help me make a decision:- 1. Is the new base 27" iMac likely to remain at the same price point as it is now? 2. Are the SSD drives likely to be standard on some of the new models, or a cheaper option than they currently are, if not? 3. I have a 23" Aluminium Apple Cinema Display - I've yet to try a 21.5" iMac (I will this weekend): will the slightly smaller screen be a really noticeable difference? The 27" is nice, but I have a relatively shallow desk, and to be honest the 23" seems perfectly sized for my uses - 27" would be a good bit bigger, and I don't need the additional screen size. 4. Assuming I don't get the SSD, would I really notice a huge speed difference in day-to-day use? The main things I do are Mail, iCal, Safari, iPhoto, and light use of Adobe InDesign/Illustrator/Photoshop (nothing too intensive or taxing). I occasionally also use Logic and other music apps, but, for comparison, my MacBook Pro handles everything I want with these absolutely fine. I'm just wanting some more responsiveness and speed from my computer - apps opening quicker, moving around in e.g. large emails (with attachments) quicker and without the delays I'm currently getting; Photoshop and InDesign more responsive and quicker/more fluid to work with. Is the iMac (without SSD) a good option? I'd love the SSD, but for an extra £400 at present (assuming the new ones are the same price), it's too much for me to pay. Any help welcome.
