If you're looking at a 45 minute commute, most of Hong Kong is within reach of Central. Our underground (MTR) is pretty efficient and so are the ferries which can bring you in from most of the outlying islands in 30-45 minutes.
My question to you would be, "Do you want to live like most of Hong Kong does or do you want to live like the stereotypical expatriate community does?".
Here are some options:
The obvious is
mid-levels, where there is a large collection of expats. Its close to SOHO and Lan Kwai Fong which are the expat drinking and dining areas. Parts of mid-levels are within walking distance of Central and Admiralty. Mid-levels is usually the choice of most mid-income expatriates who want to be close to work. Budget about HK$20K (all inclusive + cost of a part time helper) for a 700sq ft 2 bedroom apartment on the mid-range. Lower if you go for one of the older flats.
Then there is Admiralty, which is mostly a commercial area and has a few residential options. (

Wanchai, on the lower end, but there are some good new buildings. Budget about HK$15K or so.
Discovery bay, which is family oriented and home of many an expat banker who lost their housing allowances. (Inside joke) Budget about HK$15K for a 800 sq ft flat with a sea-view.
TST has some good options which a pretty decent view of Hong Kong. Again in about HK$15K range.
You have Happy Valley where you can find a decent apartment with race-course views. Again around HK$15K range.
If you want more exotic islands the price drops for housing in Lamma, Cheung Chau etc.
Don't get into a rush to make a decision. Stay in a serviced apartment for a month and make a decision.
I'm generally against serviced apartments as you have virtually no flexibility in terms of bringing your own stuff in.. and they generally cost twice as much as unserviced rentals.
Good sites to look at
www.gohome.com.hk -- HK's biggest housing / rental website.
www.hongkonghomes.com -- Higher end estate agent but they have good descriptions of the various areas.
www.wikipedia.org/wiki/Hong_Kong -- Wikipedia is an open source encyclopedia and I'm a big fan .. great articles on HK which are fairly recent.
