True. But many, including myself, think that SLT viewfinders are the future. When they first appeared they were quite poor compared to optical viewfinders, but Sony have raised the bar. Look at some reviews for this camera and you will see only positive comments. I personally think that the hybrid viewfinders ala fuji X100 are the future, that way you get the best of both worlds.
At each price point Sony are as good as any other makes. In fact the lower range Canon models do seem to me to be 'made to a price'. The middle to high range models though are excellent. If you do consider a SLR also look at the Pentax K-r. Super camera and excellent value for money. Bear in mind though, that if you do go down the SLR/SLT route, that's only the start of the spending. As mentioned consider a good bridge type camera such as those by Fuji, Canon & Panasonic.
I certainly hope that EVF's are not the future! TBH I don't much care about reviews, I care about first hand experience from using the SLT's and they don't exactly get rave reviews in that sense.
EVF's may have come on considerably, although I can't see it, the EVF on an SLT-a55 behaves exactly the same way as the EVF on my 9 year old Fuji Finepix S5000, its just too slow to respond and makes you feel detached from the image your taking. Not to menton the incresed noise reduction thats required because the translucent mirror cuts 1/3rd of the light going to the sensor.
The problem with the pentax is that your quite limited with lenses, there really aren't that many decent ones.
Seriously, if you want a DSLR the only way to go is nikon or Canon.
If you want a CSC, not a bridge, then the only way to go is with micro 4/3rds, i.e. panasonic or olympus.
there's no point buying a bridge anymore, they're too limited and CSC's aren;t that much more expensive.
For just starting out you could look at;
Nikon
D3100
D5100
canon
EOS 1100D
EOS 550D
Olympus
EPL1
EPL2
EPL3
there's a few newer ones too.
or any of the panasonic G series or GH series.

or google digital rev, they are a company based in Hong Kong, which is a turn off for most people I know, but they usually have excellent prices and are uber-reliable.
I bought a lens and a battery grip for my camera from them about 8 months ago, if I had bought it from WEX then it would have cost me 1200 quid, I got it for £700 which included the postage/import fees!
