Is it worth buying the 2011 iMac with the current specs?

[MarcoMerlin]

I need to substitute my late 2007 MBP, and I decided that I'll switch back to a desktop computer - a.k.a. iMac. But I've been researching the last iMac updates and realized that, despite the advances in processor speed (Core 2 Duo to i3, i5 and i7) and in RAM speed (1.066 to 1.333mhz), the basic specs remain the same for the entry model: 4GB RAM and 500GB HDD.
It´s been the same for the last 3 "generations", since the introduction of the unibody model, 2 years ago.
So I wonder: should I wait a little more? I fear buying an iMac now and, in 9 or 10 months, see a 8GB RAM and 750GB or 1TB HDD becomingo available as entry model.
I really need to replace my MBP, but maybe I can try to hold on a little longer.
Thanks for any tips!

RAM and HD space can always be added or replaced later on so there is no need to worry. 8GB of RAM in iMac costs 40$ and a 1TB external HD costs 50$. CPU and GPU cannot be easily replaced.

You can add additional RAM quite easily and 8GB RAM currently costs less than 100€.
With the new iMacs having Thunderbolt and external TB HDDs or enclosures probably being available in June, it is quite easy to add additional storage capacity.
If you need now, buy now. The next update will most likely happen in 2012, maybe in late 2011.

Well do you need more than 500 gigs?

Are you against external storage?

You are aware that a 5 year old could install more ram in an iMac, right? And tripling the ram from 4 to 12 gigs only runs $90 with 3rd party ram. iMacs can take up to 32 gigs of ram if you have the cash.
