I'll give you my feedback.
HelloL
I want to share with you my feedback.
I was the owner of the top of the line MBP 17" running 3.06. My reasoning at the time was to purchase the Macbook with the 8 hour battery. When they first came out, I bought the 2.66 ghz (upgraded the processor and the screen). When the next one came out, I sold it and upgraded to the 2.8 (upgraded the processor to 3.06 and screen). Once the 15 inch MBP came out with new battery, I decided that when a refresh happens I'll sell my 17" and get 15" , so when I heard the new ones were coming out. I sold mine a month ago and borrowed my 4 year old nephew's Core Duo (not core 2 duo) 2.0ghz 4 year old MacBook.
Note Core 2 duo is rated 35 percent faster than core duo technology.
I synced my old hard drive via Time Machine and I've been using it the last month.
I am missing many things, but speed isn't one of them. I was using Photoshop CS4 the other day and I didn't notice a big speed difference using the software to edit photos. I wasn't in the least bit disappointed. So I tried out my girlfriend's MacBook Pro unibody 2.26 and compared the two. Again, the speed difference was significant enough for me to justify speeding $2000 more top of the line 17". I will say that you can push hard by using snow leopard and A/V editing software. But most of the time I'm using the net, managing projects, running fusion etc.
The obvious cons when comparing the old Macbook to a new MacBook Pro were:
-Screen was inferior to LED tech in new models
-Ram maxes out at (3GB not the 2GB as advertised)
-Hard Drive size is only 80Gig
-lack of Unibody construction
-Non-lit keys (apple should just make it standard)
Conclusion:
It is hard to buy a slow computer these days especially an Apple. The OS is so fine tuned the hardware you should be pleased with the performance of any of their machines. But we have no idea what Apple has in store with the new technology. I will buy an entry level 13" or 15" the next time I buy. It fits my needs and my budget and are a ton cheaper.
You may miss out on new features in the next generation (something like hdmi, blu-ray,better battery-life, touch-screen). But ask yourself do you need the new features. Will it change the way you do computing? Are you Apps noticeably faster? Is it worth more than your spending? If the laptop your looking at now meets your needs, I say buy and save money!
