go for the computer definetly, Theres a lot of problems with the Ti right now and access havent finished solving them yet.
And its no were near as totally intergrated as they made it out to be either, i own the virus C and pre orderd a Ti late last year, ended up cancelling it beggining of this year after it was delayed and im glad i did, theres major problems with sync in Ti mode, theres only 4 simultanious outputs in Ti mode also, when i expected it to be the full 16 parts. ridiculous of them i think.

If i were you id invest my money in a powerful and stable music pc then either a) buy a second hand virus B or C for a couple of hundred quid or b) invest in a powercore card and virus plug in and have real intergration instead of the Ti's wobbly effort.

No doubt access will sort out the problems a few os updates down the line or via a hardware recall but untill then i wouldnt fork out 1200 quid for one and i the fact theyd release a peice of hardware so buggy for so much money is plain cheeky.
