I'd also like a bit more info before making a decision - except to say that there appears no value in any 21' configuration so far.
Speaking of the 27', can someone advise on the expected price for chip upgrades? The mini only cost $100 to go from i7 2.3Ghz to i7 2.6Ghz (geekbench suggests hardly even worth it). What is it likely to cost to go from i5 3.2Ghz to i7 3.1Ghz?
Will the drive be easy enough to self replace on a 27' (like the mini)? If so, why are otherwise intelligent people talking about fusion or slow and expensive apple ssd options? Wouldn't you take the standard hdd, buy SSD to install, and have the standard hdd for external use?

You should at least think about a mini - if you are on that sort of budget. $799 starting price, dyi RAM upgrade, dyi SSD upgrade, decent 24' monitor - faster computer, less cost, more customisable to your needs.

Upgrading from a Dell Latitude D620, do you think would be worth getting the base 21.5" model or a higher spec refurb 2011 model, if my budget is about $1299? Also, is there a significant different between the 640M and 650M that would make it worth it spending a little more and getting the $1499 21.5"?
